Herniaria Glabra.–These dwarf carpeting plants are of easy culture. Grow from seed in spring and transplant into sandy soil. Height, 1-1/2 in.

Hesperis.–_See_ “Rocket.”

Heuchera.–Very neat, but not showy, hardy American perennials. They may be grown in any ordinary light garden soil, are increased by dividing the root, and bloom in May. Height, 1 ft. to 2 ft.

Hibbertia Dentata.–An evergreen twining plant, requiring a greenhouse for its cultivation and a soil of sandy loam and peat. It flowers in July, and is increased by cuttings taken in spring or summer and kept under glass. Height, 6 ft.

Hibiscus Africanus.–A handsome hardy annual Mallow. Sow in March in slight heat, and plant out in May 10 in. apart. Grows best in a mixture of loam and peat. Blooms in June. Height, 2 ft.

Hibiscus Syriacus (_Rose of Sharon_).–A hardy, deciduous, autumn-flowering shrub, which will grow in common soil, and may be propagated by seeds, layers, or cuttings planted under glass. Height, 6 ft.

Hieracium (_Hawkweed_).–A free-growing hardy perennial, suitable for a sunny bank or border. It is not particular as to soil. From June to September it produces orange-brown flowers. It grows freely from seed, and the roots bear division. Height, 1-1/2 ft.

Hippeastrums.–_See_ “Amaryllis.”

Hippocrepis.–Very pretty hardy trailing perennials, covered from May to July with golden Pea-shaped flowers. They will grow in any light, sandy soil, and may be increased by cuttings, which root readily under glass. Height, 3 in. to 6 in.

Hippophae.–Ornamental shrubs, thriving in ordinary soil, and increased by layers or cuttings of the roots. H. Rhamnoides (Sea Buckthorn) flowers in May. Height, 12 ft.

Holboellia Latifolia.–_See_ “Stauntonia Latifolia.”

Holly (_Ilex_).–This pleasing hardy evergreen shrub thrives best on a deep, sandy loam, but will grow in any good soil, provided the position is dry. It succeeds well in the shade. Cuttings of young shoots having 1 in. of the old wood attached will strike root, but the plant is of very slow growth, and takes at least four years to grow into a good bush. Choice varieties may be grafted or budded on to the common sorts in June or July. To grow Holly from seed, gather the berries when ripe, crush them, and mix them up with a little sandy loam, bury them in a hole 3 ft. deep, and cover with litter. Dig them up and sow them in March. Big bushes are best moved at the end of August, mixing the earth to a puddle before planting. The less pruning they receive the better. They may be trimmed in spring.

Hollyhock.–May be raised from seed or cuttings. Sow the seed about the second week of March in very rich soil, and cover it with 1 in. of dry earth. In June (having soaked the bed thoroughly overnight) remove the young plants to a nursery-bed, setting them 6 in. apart. Press the earth firmly round the roots, and water plentifully until settled. In the autumn plant them where they are to bloom. Cuttings may be taken as soon as the flowers appear, or from the old plants in autumn. Each joint having an eye will furnish a plant. Select side branches having two or three joints and leaves. Cut the shoots through just under the lower joint, leaving the leaf entire; cut it also about 2 in. above the joint. Plant in equal parts of loam, gritty sand, and leaf-mould; shelter from the sun, and sprinkle them every day in fine weather with water. If the cuttings are taken in autumn pot them off in 60-sized pots, and keep them in a cold frame till the spring, when they may be planted out. Flowers in August. Height, 6 ft.

Homerias.–Beautiful little South African plants. For out-door cultivation plant the bulbs in a dry, warm situation, from October to January, 3 in. deep, and the same distance apart, in rich, light, well-drained soil, and protect them from heavy rains with a good layer of leaves. For pot culture put four or five bulbs in a 5-in. pot, place in a cold frame, and cover with cocoa-nut fibre until the growth appears. Water moderately, and when the flowers fade abstain from supplying moisture. The bulbs are not quite hardy, therefore they should be removed indoors before frosts appear.

Homogyne Alpina.–Hardy herbaceous plants flowering in April. Any soil is suitable for them, and they may be increased by division. Height, 6 in.

Honesty (_Lunaria_).–Interesting hardy biennials. When dried, the shining seed-pods make a handsome addition to winter bouquets, mixed with ornamental grass. Any common soil suits them. Sow the seed any time from April to June, and transplant them to the border in the autumn for flowering the following May. Height, 1-1/2 ft. to 3 ft.

Honeysuckles.–These rapid twiners thrive in any loamy soil, and may be increased by putting down layers in the autumn, after the leaves begin to fall. They can also be propagated by cuttings taken in the autumn and planted in a shady, sheltered spot. Caprifolium Brachypoda and the evergreen C. Sempervirens are handsome, free-flowering kinds, suitable for almost any situation. C. Aurea-reticulata has beautifully variegated leaves, which render it very ornamental. Height, 6 ft. to 8 ft.

Hop.–A useful hardy climber for covering verandahs, summer-houses, etc. Plant in rich, loamy soil, and increase by dividing the roots. (_See also_ “Humulus Japonicus.”)

Hordeum Jubatum (_Squirrel-tail Grass)_.–A very pretty species resembling miniature barley. Sow seed in March, covering it very lightly, and keep the surface of the soil moist till the grass appears. Height, 1-1/2 ft.

Horminum Pyrenaicum.–This hardy perennial produces erect white flowers with blue corolla in June or July. It will grow in any ordinary soil, but needs protection in winter, as it is apt to be injured by damp. It may be propagated either by seed or division. Height, 1-1/2 ft.

Horn Poppy.–_See_ “Glaucium.”

Horseradish.–Plant in October or February in deep, rich soil; or it may be grown on a heap of cinder-ashes, or on any light ground through which the roots can make their way readily. The best way to increase it is by slips taken from the roots. It requires little or no attention beyond pinching out the tops when running to seed and keeping the ground hoed.

Hotbeds, to Make.–Take dead leaves and stable-straw, with the dung, in the proportion of two double loads for a three-light frame. Turn it over four or five times during a fortnight, watering it if it is dry. Then mark out the bed, allowing 1 ft. or more each way than the size of the frame. Shake the compost well up, and afterwards beat it down equally with the fork. Place the frame on the bed, leaving the lights off for four or five days to allow the rank steam to escape. Keep a thermometer in the frame, and as soon as the temperature falls below 70 degrees apply a lining of fresh dung to the front and one side of the bed, and when this again declines, add another lining to the back and other side, and so on from time to time as occasion requires. The mats used for covering the frames in frosty weather should be made to fit the top, and not hang over the sides.

Houseleek.–_See_ “Sempervivum.”

Houstonia Coerulea.–These hardy little evergreens are more generally known as Bluets. They make charming ornaments for rock-work, planted between large stones, but in this position they need protection from severe frosts. When planted in pots and placed in a cold frame they show to most advantage. A mixture of leaf-mould and sand, and a moist but well-drained situation is what they delight in. They bloom continuously from April to July. Height, 3 in.

Hovea Celsi.–A greenhouse shrub, which is evergreen and elegant when in flower in June. A sandy loam and peat soil is most suitable, and it may be increased by cuttings planted in sand under a hand-glass. Height, 3 ft.

Humea.–A remarkably handsome and graceful plant, the leaves of which when slightly bruised yield a strong odour. It is equally suitable for the centre of beds or large borders, and placed in pots on terraces or the lawn it is very effective. The seed should be raised on a gentle hotbed, then potted off and kept in the greenhouse till the second year, when it may be turned out into a warm situation. It generally succeeds better in such a position than in the greenhouse. Flowers in July. Height, 6 ft. to 8 ft.

Humulus Japonicus.–(_Japanese Hop_).–A hardy annual Hop of rapid growth, the leaves of which are splashed with white. Useful for covering arbours, verandahs, etc. A deep, loamy soil suits it best. Increased by seed sown in gentle heat in February, and gradually hardened off. Flowers in July. Height, 20 ft.

Hutchinsia Alpina.–This small alpine creeper is a profuse bloomer, its glistening white flowers being produced at all seasons. It grows in moist vegetable mould, and bears transplanting at any season. Care, however, is required to prevent its roots over-running and choking other things. Height, 2 in.

Hyacinths.–May be grown in pots, in glasses, or in beds and borders. The soil should be rich and light. Good loam mixed with old manure and a little leaf-mould and sand suits them very well. If intended to be grown in pots the best time to begin potting is early in September, putting more in at intervals of two or three weeks until the end of December. One bulb is sufficient for a 5-in. or 6-in. pot, or three may be placed in an 8-in. pot. The soil under the bulb should not be pressed down. The top of the bulb should be just above the surface. Place the pots on a bed of ashes in a cold frame, put a small inverted pot over the top of the bulb, and cover the whole with cocoa-nut fibre or cinder-ashes to the depth of about 4 in. In about a month roots will have formed with about 1 in. of top growth. The plants may then be taken out, gradually exposed to the light, and finally removed to the conservatory or sunny window. The doubles do best in pots.

For growing in glasses select the firmest and best-shaped bulbs. Those with single blossoms are preferable, as they are of stronger constitution than the doubles. Fill the glasses with pure pond or rain water, so that the bulbs just escape touching it, and put a piece of charcoal in each glass, and change the water when it becomes offensive, taking care that the temperature is not below that which is poured away. Stand the glasses in a cool, dark place for three or four weeks until the roots have made considerable progress, then gradually inure to the full light. September is a good time to start the growth.

When planted in beds or borders, place the bulbs about 4 in. deep and 6 in. apart, putting a little silver sand below each one. This may be done at any time from October till frost sets in. They succeed fairly well in any good garden soil, but give greatest satisfaction when the ground is rich and light.

Hyacinthus (_Muscari_).–A very hardy race of spring-flowering bulbs. Though the varieties are very dissimilar in appearance, they all produce a good effect, especially when planted in good large clumps. Plant from September to December. A sandy soil suits them best. The following are well-known varieties:–_BOTRYOIDES_ (_Grape Hyacinth_).–Very pretty and hardy, bearing fine spikes of deep, rich blue flowers in compact clusters on a stem 6 to 9 in. high. Sweet-scented, and blooms about May. The _Alba_, or white, variety is also sweet-scented.

Hyacinthus–_continued_.

_CANDICANS_ (_Galtonia_).–The white Cape Hyacinth, or Spire Lily. A hardy, summer-flowering, bulbous plant 3 ft. to 4 ft. in height, gracefully surmounted with from twenty to fifty pendent, bell-shaped snow-white flowers. Thrives in any position and equally suitable for indoor or outdoor decoration.

_MOSCHATUS_ (_Musk Hyacinth_).–Bears very fragrant purplish flowers.

_PLVMOSUM_ (_Feather Hyacinth_).–A fine, hardy, dwarf plant suitable for any soil. Its massive sprays of fine blue flowers, arranged in curious clusters, 5 to 6 in. in length, resemble much-branched slender coral.

_RACEMOSUM_ (_Starch Hyacinth_).–Rich dark-blue or reddish-purple flowers. Very free-flowering and fine for massing. It is similar to the Cape Hyacinth, but flowers in denser spikes.

Hydrangea.–This shrub delights in a moist, sheltered position and rich soil. It may be increased at any time from cuttings of the young side-shoots, 2 or 3 in. long, under glass, in sandy soil. The old stems will also strike if planted in a sheltered situation. The plants should be cut back when they have done flowering, and protected from frost; or they may be cut down to the root and covered with manure. They are well suited for the front of shrubberies, and also make fine plants for pot cultivation. The flowers are produced in June and July. Height, 3 ft.

Hymenanthera Crassifolia.–Ornamental evergreen shrubs, thriving best in a compost of loam and peat. They are increased by cuttings planted in sand and subjected to a little heat. Height, 6 ft.

Hymenoxys.–Pretty little hardy annuals that may be easily raised from seed sown early in March in any garden soil. They bloom in June. Height, 1 ft.

Hypericum (_St. John’s Wort_).–Favourite dwarf shrubs. Any soil suits the hardy kinds, but they prefer shade and moisture. These may be increased by seed or division. The greenhouse varieties thrive best in a mixture of loam and peat. Young cuttings placed in sand under glass will strike. July is their flowering season. Height, 1-1/2 ft. to 2 ft.

I

Iberis.–_See_ “Candytuft.”

Ice Plants.–_See_ “Mesembryanthemum.”

Ilex.–_See_ “Holly.”

Impatiens Sultani.–Half-hardy perennials. May be raised from seed sown early in spring on a hotbed, or later on in a shady spot in the open border; greenhouse culture, however, is more suitable. They bloom in August. Height, 11/2 ft.

Incarvilleas.–Ornamental hardy herbaceous plants, of easy culture. They are suitable for the border or the rockery, and will grow in any soil if not too dry and exposed. The tuberous roots may be planted at any time in autumn, 4 in. deep. I. Delavayi makes a fine solitary or lawn plant, its leaves being from 1 to 3 ft. long; the soft rose-pink, Mimulus-shaped flowers, which are carried on stout stems well above the foliage, appearing in May. Care should be taken not to disturb it in spring, and it is advisable to cover the roots in winter with a pyramid of ashes, which may be carefully removed at the end of April. Incarvilleas may be propagated by seed sown, as soon as it is ripe, in light, well-drained soil, giving the young plants protection in a frame during the first winter, with enough water merely to keep them moist. Height, 2 ft.

Indian Corn.–_See_ “Zea.”

Indian Shot.–_See_ “Canna.”

India-rubber Plants.–_See_ “Ficus.”

Indigofera.–Beautiful evergreen shrubs. I. Australis has elegant, fern-like foliage and racemes of pink or purple Pea-shaped flowers in April. I. Decora Alba bears its white flowers in July. They require a sandy loam or peat soil, and greenhouse culture. Cuttings of the young wood planted in sand under glass will strike. Height, 21/2 ft.

Insects on Plants.–To destroy insects on plants wash the plant with Tobacco-Water (_which see_). Or put 1 oz. of quassia chips in a muslin bag, pour on some boiling water, and make it up to I gallon; dissolve 1 oz. of soft soap, add it to the chips, and stir well. Use it two or three times during spring and early summer.

Inula Royleana (_Fleabane_).–A hardy perennial which flowers in November. It will grow in any garden soil, and can be increased by seeds, or by division of the roots. Height, 3 ft.

Ionopsidium.–These hardy annuals grow freely in any rich, damp soil; a shady position is indispensable. Height, 1/8 ft.

Ipomoea.–These beautiful climbing plants are very suitable for covering trellis-work, or for the pillars or rafters of the stove-house. The seed is generally sown in April on a hotbed or under glass, and the young plants set out in the border of the house in May in light, rich soil. Success is mainly secured by allowing plenty of root-room. The perennial kinds are increased from cuttings taken from the small side-shoots placed in sand in a brisk bottom-heat. If grown in the open they often shed their seed, and come up year after year with but little attention. They make a good contrast to Canariensis. The Ipomoea Horsfalliae, with its bright scarlet flowers, has a lovely appearance, but must be treated as a stove evergreen. This is propagated by layers, or by grafting on some strong-growing kind. It thrives in loam and peat mixed with a little dung, and flowers in July or August. Height, 6 ft. to 10 ft.

Ipomopsis.–A very beautiful half-hardy biennial, but difficult to cultivate. Some gardeners steep the seed in hot water before sowing it; but the best way seems to be to sow it in July in 3-in. pots in equal parts of sandy peat and loam, ensuring good drainage, and place it in a cold frame, giving it very little water. When the leaves appear, thin out the plants to three or four in each pot. Replace them in the frame for a week or so, then remove them to a light, airy part of the greenhouse for the winter. During this period be careful not to over-water them. In spring shift them into well-drained 4-1/2-in. pots, using the same kind of soil as before, and taking great care not to injure the roots; still give the least possible amount of water. If plenty of light and air be given, they will flower in July or August. Height, 2 ft.

Iresines.–Take cuttings of these greenhouse plants in autumn; insert them thinly in 48-size pots filled with coarse sand, loam, and leaf-mould, and place in a uniform temperature of 60 or 70 degrees. When they have taken root place them near the glass. Height, 1-1/2 ft.

Iris.–The Iris is the orchid of the flower garden; its blossoms are the most rich and varied in colour of hardy plants. For cutting, for vases, table decoration, etc., it is exceedingly useful, as it is very free-flowering, and lasts a long time in water. It thrives in almost any soil, though a sandy one suits it best, and is strikingly effective when planted in clumps. It soon increases if left undisturbed. The English Iris blooms in June and July, bearing large and magnificent flowers ranging in colour from white to deep purple, some being self-colours, while others are prettily marbled. The German Iris is especially suitable for town gardens. The Spanish Iris blooms a fortnight before the English. Its flowers, however, are smaller, and the combinations of colours very different. The Leopard Iris (_Pardanthus Chinensis_)is very showy, its orange-yellow flowers, spotted purple-brown, appearing in June and July. They are quite hardy. The best time for planting them is October or November, selecting a sunny position. Height, 1-1/2 ft.

Isopyrums–Hardy herbaceous plants of great beauty, nearly related to the Thalictrums. They will grow in any ordinary soil, but flourish best in vegetable mould, and in a moist, yet open, situation. They are readily raised from seed, or may be propagated by division of the roots in autumn. They flower in July. Height, 1 ft. to 1-1/2 ft.

Ivy (_Hedera_).–A deep, rich soil suits the common Ivy; the more tender kinds require a lighter mould. To increase them, plant slips in a north border in sandy soil. Keep them moist through the autumn, and plant them out when well rooted. The following are the principal choice sorts:–Aurea Spectabilis, palmate-leaved, blotched with yellow; Cavendishii, a slender-growing variety, leaves margined with white, with a bronzy shade on the edge; Conglomerata, crumpled leaves; Elegantissima, slender-growing, with silvery variegated leaves; Irish Gold-Blotch, large leaves, blotched with yellow; Latifolia Maculata, large white-blotched leaves; Lee’s Silver, silver variegated; Maderiensis Variegata, leaves broadly marked with white; Marmorata, small leaves blotched and marbled with white; Pupurea, small leaves of a bright green changing to bronzy-purple; Rhomboides Obovata, deep green foliage; Rhomboides Variegata, greyish-green leaves, edged with white; and Silver Queen, a good hardy variety.

Ixias.–Plant out of doors from September to December, in a sunny, sheltered position, in light, rich, sandy soil. For indoor cultivation, plant four bulbs in a 5-in. pot in a compost of loam, leaf-mould, and silver sand. Plunge the pot in ashes in a frame or cold pit, and withhold water until the plants appear. When making free growth remove them to the conservatory or greenhouse, placing them near the glass, and give careful attention to the watering. Ixias are also known under the name of African Corn Lilies.

J

Jacobaea (_Ragwort_).–May be raised from cuttings in the same way as Verbenas, and will grow freely from seeds sown in autumn or spring. It delights in a rich, light soil. The purple Jacobaea is a great favourite of the public. Flowers in August. Height, 1 ft.

Jacob’s Ladder.–_See_ “Polemonium.”

Jasione Perennis (_Sheep Scabious_).–A hardy perennial which produces a profusion of heads of blue flowers in June, and continues to bloom till August. It enjoys a peat soil, and should have the protection of a frame during the winter. It can be propagated by seeds, cuttings, or division. Height, 1 ft.

Jasminum.–These are favourite plants for training over arbours or trellis-work, and for growing against walls. The hardy kinds will flourish in ordinary soil. The stove and greenhouse sorts should be provided with a mixture of sandy peat and loam. They may all be increased by cuttings of ripened wood planted in a sandy soil under glass. J. Nudifolium produces an abundance of bright flowers after its leaves have fallen, and is very suitable for town gardens. J. Unofficinale is likewise adapted for town, bearing confinement well, and has very sweet flowers. J. Revolutum needs protection in severe weather. They bloom in July. Height, 12 ft.

Job’s Tears.–_See_ “Coix Lachryma.”

Jonquils.–These are quite hardy, and may be grown in the open in the same manner as Hyacinths. Five or six bulbs in a 5-in. pot make a very pretty bouquet. They are excellent early flowers, and very odoriferous. Plant in autumn, placing sand round the bulbs. Best not disturbed too often. The leaves should not be cut off when withering, but allowed to die down. They bloom in April. Height, 1 ft.

Joss Flower.–_See_ “Chinese Sacred Narcissus.”

Juniper (_Juniperus_).–These useful conifers prefer dry chalk or sandy soils, but will thrive in any ground that is not too heavy. J. Japonica, Sabina, and Tamariscifolia do well on steep banks and rock-work. They may be propagated by seeds, grafting, or by cuttings of firm young shoots planted in a sandy compost, kept shaded, and covered with a hand-glass.

K

Kadsura Japonica.–This is a beautiful creeper for a south or west aspect. It thrives best in loam and sandy peat. Cuttings may be struck in sand, placed under a glass, and subjected to heat.

Kale.–_See_ “Borecole.”

Kalmia Latifolia.–This hardy, dwarf evergreen shrub is deservedly a great favourite. It produces a wealth of flowers in large clusters. It requires to be grown in peat or good leaf-mould, and needs pure air. It is increased by pegging down the lower branches, which soon become rooted. The flowers are produced from June to August. Height, 2 ft.

Kalosanthes.–Showy greenhouse succulent plants. A light, turfy loam is suitable for them, and they may be increased by placing cuttings of the young shoots in a sandy soil on a slight hotbed in spring. Pinch them back so as to produce a bushy growth, and give support to the heavy heads of bloom. The cuttings should be left for twenty-four hours to dry before they are planted. The plants require very little water, and they flower in July. Height, 6 in. to 1 ft.

Kaulfussia.–Sow this pretty hardy annual in April in the open border, or in March in slight heat. It may also be sown in autumn for early flowering. It will succeed in any light soil, blooming in July. Height, 6 in.

Kennedya Marryattae.–A greenhouse evergreen twining plant of a very beautiful order, which thrives best in a compost of sandy loam and peat. Cuttings of the young wood planted in sand, and having a bottom-heat, will strike. It produces its flowers in May. Height, 4 ft. Other varieties of Kennedyas range from 2 to 10 ft. They all need to be well drained and not to stand too near the pipes.

Kerria (_Corchorus_).–Beautiful hardy shrubs, which may be grown in any garden soil, and can be propagated by cuttings of the young wood, taken at a joint, and placed under glass. They flower at midsummer. Height, 4 ft.

Koelreuteria Paniculata.–This is an ornamental tree bearing long spikes of yellow flowers in July. It will grow in any soil, but requires a sheltered position, and may be increased by layers or root cuttings. Height, 10 ft.

Kohl Rabi (_Turnip-rooted Cabbage_).–Though mostly grown as a farm crop, this vegetable is strongly recommended for garden cultivation, as it is both productive and nutritious, and is delicious when cooked while still very small and young. Sow in March, and transplant to deeply-dug and liberally manured ground, at a distance of 15 in. from each other.

L

Lachenalia. (_Cape Cowslips_).–Charming greenhouse plants for pot or basket culture. Pot in December in a compost of fibrous loam, leaf-mould, and sand; place as near the glass as possible, and never allow the soil to become dry, but maintain good drainage, and only give a little water till they have produced their second leaves. No more heat is required than will keep out the frost.

Lactuca Sonchifolia. (_Sow Thistle-Leaved Lettuce_).–An ornamental, but not handsome, hardy perennial, with leaves 1 ft. in length and 9 in. in breadth. It is of neat habit and enjoys the sunshine. A deeply-dug, sandy loam suits it, and it may be increased by seed or division of the roots. The flowers are produced from September till frost sets in. Height, 2 ft.

Ladies’ Slipper Orchid.–_See_ “Cypripedium.”

Lady’s Mantle.–_See_ “Alchemilla.”

Lagurus Ovatus.–This hardy annual is commonly known as Hare’s-Tail Grass. It is distinctly ornamental, producing elegant egg-shaped tufts of a silvery-white hue, and is fine for ornamenting bouquets. Sow in March, and keep the ground moist till the seed germinates. Height, 1 ft.

Lallemantia Canescens.–Bees are very fond of this blue hardy annual, which may readily be grown from seed sown in the spring. Height, 1 ft.

Lamium.–These plants are mostly of a hardy herbaceous description and of little value. They will grow well in any kind of soil, flowering from March to July, according to their varieties, and can be propagated by seed or division. Height, 6 in. to 1 ft.

Lantana.–These dwarf, bushy, half-hardy perennial shrubs bear Verbena-like blossoms. They like a dry and warm situation and rich, light soil. The seed is sown in March to produce summer and autumn blooming plants. If cuttings are placed in sand, in heat, they will take root easily. Height, 1 ft. to 1-1/2 ft.

Lapageria Rosea.–A beautiful climbing plant which bears large rose-coloured flowers in May. It can be grown in any light, rich soil, but a compost of leaf-mould, sand, and peat suits it best. It makes a very desirable greenhouse plant, and can be increased either by cuttings or by division. Lapagerias require partial shade, plenty of water, and good drainage. Height, 10 ft.

Lardizabala Biternata.–This climbing shrub has fine ornamental foliage. It is most suitable for a south or west aspect, where it proves hardy; in other positions protection should be afforded. It will grow in any good soil. May is the month in which it flowers. Height, 20 ft.

Larkspur.–The Stock-flowered Larkspur is of the same habit as the Dutch Rocket, but has longer spikes and larger and more double flowers. The Hyacinth-flowered is an improved strain of the Rocket. Among other of the hardy annual varieties may be mentioned the Candelabrum-formed, the Emperor, and the Ranunculi-flowered. They are charming flowers for beds or mixed borders, and only require the same treatment as ordinary annuals, when they will flower in June. Height, 1 ft. to 2-1/2 ft. For perennial Larkspurs, _see_ “Delphinium.”

Lasiandra.–Stove evergreen shrubs, flourishing best in a mixture of equal parts of loam, peat, and sand. They are propagated by cuttings of the young wood, plunged in heat. July is their flowering month. Height, 5 ft.

Lasthenia.–A hardy annual of a rather pretty nature, suitable for flower-beds or borders. Autumn is the best time for sowing the seed, but it may also be sown early in the spring. It blooms in May. Height, 1 ft.

Lathyrus.–Handsome plants when in flower, the larger kinds being well adapted as backgrounds to other plants in the shrubbery, where they will require supports. They may be planted in any garden soil, and can be increased by seed, and some of the perennial kinds by division of the root. L. Latifolia (Everlasting Pea) flowers in August, other varieties at different times, from May onwards. Height, 1 ft. to 8 ft.

Laurel.–Laurels will grow in any good garden soil. They are grown both as bushes and standards, and require but little attention beyond watering. The standards are produced by choosing a young Portugal plant and gradually removing the side-shoots on the lower part of the stem, and when the desired height is reached a well-balanced head is cultivated, any eyes that break out on the stem being rubbed off with the thumb. Lauro Rotundifolia is beyond dispute the best of all Laurels; it is of free growth and of dense habit, and its leaves are roundish and of a lively green. (_See also_ “Epigaea.”) All Laurels may be propagated by cuttings and by layers, the latter being the plan usually adopted.

Laurestinus.–_See_ “Viburnum Tinus.”

Laurus.–_See_ “Bay, Sweet.”

Lavatera.–The greenhouse and frame kinds grow in any light soil, and are increased by cuttings of the ripened wood, under glass. The hardy herbaceous species grow well in any common soil, and are propagated by seeds or division. The annuals are sown in the open in spring. Some bloom in June, others as late as August. Height, 2 ft. to 5 ft.

Lavender (_Lavandula Spied_).–A hardy shrub whose sweetly-scented flowers, which are produced in August, are much prized. A dry, gravelly soil is what it likes best. Young plants should be raised every three years. It is readily propagated from seed sown in spring. Cuttings about 8 in. long, taken in autumn and planted 4 in. deep under a hand-light or in a shaded, sheltered position, will strike. Height, 1-1/2 ft.

Lawns–To make or renovate Lawns sow the seed on damp ground during March or April, if possible, but in any case not later than September, as the young plants are easily ruined by frost. Rake the seed in lightly, afterwards roll with a wooden roller, and carefully weed the ground until the grass is well established. To form a thick bottom quickly on new Lawns sow 60 lbs., or 3 bushels, to the acre; for improving old ones, 20 lbs. per acre. Frequent cutting and rolling is essential to success. If the grass is inclined to grow rank and coarse it will be much improved by a good dressing of sand over it; if it has an inclination to scald and burn up, sprinkle it with guano or soot just before a shower of rain. An accumulation of moss upon a lawn can only be cured by under-draining.

Lawns, Shrubs for.–_See_ “Shrubs for Lawns.”

Layering.–_See under_ “Carnations.”

Ledum (_Labrador Tea_).–Low-growing American evergreen shrubs, thriving best in sandy peat, and may be increased by layers.

Leek.–Sow early in March, and prick out the plants in rich soil, in a sheltered position, to strengthen. As soon as they are large enough, plant them out in very rich, light ground in drills 6 in. between each plant and the rows 18 in. apart. For large exhibition Leeks sow in boxes in February, under glass. Plant out in June in trenches 15 in. wide and 18 in. deep, with plenty of old manure at the bottom of the trench and 6 in. of good light mould on the top of it. Gradually earth up as the stems grow. Water liberally in dry weather, and give a little weak liquid manure occasionally.

Leontopodium.–Hardy perennials, succeeding best in peat soil. They are most suitable for rock-work, and may be increased by seed or division of the roots. Bloom is produced in June. Height, 6 in.

Leopard’s Bane.–_See_ “Doronicum.”

Leptosiphon.–Charming hardy annuals which make nice pot-plants. The seed should be sown in rich, light soil–peat for preference. If this is done in autumn they will flower in April and May; if sown in spring they will bloom in autumn. They are very attractive in beds or ribbons, and also on rock-work. Height, 3 in. to 1 ft.

Leptospermum.–Neat greenhouse evergreen shrubs, most at home in equal portions of loam, peat, and sand. Cuttings may be struck in sand under glass. They flower in June. Height, 4 ft. to 5 ft.

Leschenaultia.–Elegant greenhouse shrubs, delighting in a mixture of turfy loam, peat, and sand. They are evergreen, flower in June, and are propagated by cuttings of the young wood under glass. Height, 1 ft.

Lettuce.–Sow early in February on a slight hotbed, and prick out into a well-manured and warm border, having the soil broken down fine on the surface. For early summer supplies sow outdoors in March, and at intervals till the middle of September for later crops. Some of the plants raised in September should be wintered in a cold frame, and the remainder transplanted to a dry, sheltered border, or protected with hand-lights. The June and July sowings may be made where the plants are intended to remain. They should stand from 6 to 9 in. apart. A north border is a suitable position in the summer months, as they are less exposed to the sun, and do not run to seed so quickly. The Cos Lettuce requires to be tied up to blanch; this should be done ten days before it is wanted for use. Cabbage Lettuce does not need to be tied.

Leucanthemum (_Hardy Marguerites_).–Same treatment as Chrysanthemum.

Leucojum (_Snowflake_).–Also known as St. Agnes’ Flower. Handsome plants. The flowers are pure white, every petal being tipped with green, dropping in a cluster of from six to eight blooms, each nearly 1 in. long. They grow freely in almost any soil, sandy loam being preferable. Increased by off-sets from the bulb, or by seed as soon as it is ripe. The spring snowflake blooms in March, the summer variety in June. The latter is a much more vigorous plant than the former. Height, 12 in. to 18 in.

Leucophyton Browni.–A popular white-foliaged bedding plant, which may be increased by dibbling cuttings in sandy soil and placing them in a cool frame.

Lewisia Rediviva.–This makes a pretty rock-plant. It is a perennial and quite hardy, but requires plenty of sun. During April and May it produces large flowers varying in colour from satiny rose to white. The most suitable soil is a light loam mixed with brick rubbish. It is increased by division of the root, or it may be raised from seed. Height, 3 in.

Leycesteria Formosa.–Ornamental plants, the flowers resembling Hops of a purple colour. They will grow in any soil, but need protection in winter. They are multiplied by cuttings. Height, 3 ft.

Liatris Pycnostachya.–A curious old herbaceous perennial, now seldom met with, sending up late in summer a dense cylindrical purple spike 2 ft. high. It needs a rich, light, sandy soil, and to be protected during the winter with a thick covering of litter. The roots may be divided in the spring. Height, 3 ft.

Libertia Formosa.–The narrow foliage and spikes of pure white flowers, produced in May and June, render this hardy perennial very ornamental. The soil should consist of equal parts of loam and peat. It is propagated by dividing the roots. Height, 1 ft.

Libonia Floribunda.–This is a winter-flowering plant, and is easily grown in a cool greenhouse. It is very useful for table decoration, its slender red and yellow tubes of bloom being very effective, but it does not do to keep it for any length of time in a room where there is gas. When flowering has ceased, encourage new growth by giving it plenty of water, air, and sunlight. The new shoots should be cut back in May, and the tips of them used as cuttings, which strike readily in good mould. Height, 2 ft.

Ligustrum _(Privet)._–L. Ovalifolium is a handsome hardy evergreen, of very rapid growth, and one of the best ornamental hedge plants in cultivation, especially for towns or smoky situations. L. Japonicum is likewise ornamental and hardy: Tricolor is considered one of the best light-coloured variegated plants grown. L. Coriaceum is a slow-growing, compact bush with very dark, shining green leaves, which are round, thick, and leathery. Privet will grow in any soil or situation, and is readily increased by cuttings planted in the shade in spring.

Lilac–_See_ “Syringa.”

Lilium.–The Lily is admirably adapted for pot culture, the conservatory, and the flower border, and will flourish in any light soil or situation. To produce fine specimens in pots they should be grown in a mixture of light turfy loam and leaf-mould. Six bulbs planted in a 12-in. pot form a good group. The pots should have free ventilation, and the bulbs be covered with 1 in. of mould. For outdoor cultivation plant the bulbs 4 to 5 in. deep, from October to March. After once planting they require but little care, and should not be disturbed oftener than once in three years, as established plants bloom more freely than if taken up annually. Give a thin covering of manure during the winter. Lilium seed may be sown in well-drained pots or shallow boxes filled with equal parts of peat, leaf-mould, loam, and sand. Cover the seeds slightly with fine mould and place the boxes or pots in a temperature of 55 or 65 degrees. A cold frame will answer the purpose, but the seeds will take longer to germinate. The Lancifolium and Auratum varieties have a delicious fragrance.

Lilium–_continued_.

_CANDIDUM_ (the Madonna, or White Garden Lily) should be planted before the middle of October, if possible, in groups of three, in well-drained, highly-manured loam. Should they decline, take them up in September and re-plant at once in fresh, rich soil, as they will not stand being kept out of the ground long. They are increased by off-sets. As soon as these are taken from the parent bulb, plant them in a nursery-bed; after two years they may be transferred to the garden. This Lily is quite hardy, and needs no protection during winter.

_LANCIFOLIUM_ make very fine pot-plants, or they may be placed in a sunny situation in the border, but in the latter case they must have a thick covering of dry ashes in winter. If grown in pots place them, early in March, in rich, sandy soil. Three bulbs are sufficient for an 11-in. pot. Give very little water, but plenty air in mild weather. Let them grow slowly. When all frost is over place pans under them, mulch the surface with old manure, and supply freely with air and water. They are propagated by off-sets.

_MARTAGON_ (or Turk’s Cap) requires the same treatment as the Candidum, with the exception that a little sand should be added to the soil.

_TIGRINUM_ (Tiger Lily) also receives the same treatment as the Madonna. When the flower-stems grow up they throw out roots. A few lumps of horse manure should be placed round for these roots to lay hold of. They are increased by the tiny bulbs which form at the axis of the leaves of the flower-stem. When these fall with a touch they are planted in rich, light earth, about 6 in. apart. In four or five years’ time they will make fine bulbs.

_AURATUM_ and _SZOVITZIANUM_ (or Colchicum) thrive best in a deep, friable, loamy soil, which should be well stirred before planting. If the soil is of a clayey nature it should be loosened to a depth of several feet, and fresh loam, coarse sand, and good peat or leaf-mould added, to make it sufficiently light.

For _PARDALINUM_ (the Panther Lily) and _SUPERBUM_ mix the garden soil with three parts peat and one part sand, and keep the ground moist. They should occupy a rather shady position.

All the other varieties will succeed in any good garden soil enriched with leaf-mould or well-decayed manure.

For _VALLOTA_ (Scarborough Lily), _BELLADONNA_, and _FORMOSISSIMA_ (or Jacobean) Lilies, _see_ “Amaryllis.”

For _AFRICAN LILY, see_ “Agapanthus.”

For _PERUVIAN LILIES, see_ “Alstromeria.”

For _ST BERNARD’S_ and _ST BRUNO’S LILIES, see_ “Anthericum.”

For _CAFFRE LILIES, see_ “Clivias.”

Lily of the Valley.–Set the roots in bunches 1 ft. apart, and before severe weather sets in cover them with a dressing of well-rotted manure. They should not be disturbed, even by digging among the roots. If grown in pots, they should be kept in a cool place and perfectly dry when their season is over: by watering they will soon come into foliage and flower again. For forcing put ten or twelve “buds” in a 5-in. pot–any light soil will do–plunge the pot in a sheltered part of the garden. From this they may be removed to the forcing-house as required to be brought into bloom. Plunge the pots in cocoa-nut fibre and maintain an even temperature of from 65 to 70 degrees.

Limnanthes Douglasii.–Very elegant and beautiful hardy annuals, which are slightly fragrant. They must be grown in a moist and shady situation. The seeds ripen freely, and should be sown in autumn to produce bloom in June, or they may be sown in spring for flowering at a later period. Height, 1 ft.

Linaria.–These all do best in a light, sandy loam, and make good plants for rock-work. L. Bipartita is suitable for an autumn sowing. The other annuals are raised in spring. L. Triornithophora is a biennial, and may be sown any time between April and June, or in August. The hardy perennial, L. Alpina, should be sown in April, and if necessary transplanted in the autumn. Linarias flower from July to September. Height, 6 in. to 1 ft.

Linnaea Borealis.–A rare, native, evergreen creeping perennial. From July to September it bears pale pink flowers; it makes a pretty pot-plant, and also does well in the open when planted in a shady position. It enjoys a peat soil, and is propagated by separating the creeping stems after they are rooted. Height, 11/2 in.

Linum (_Flax_).–This succeeds best in rich, light mould. The Linum Flavum, or Golden Flax, is very suitable for pot culture; it grows 9 in. in height, and bears brilliant yellow flowers. It requires the same treatment as other half-hardy perennials. The Scarlet Flax is an annual, very free-flowering, and unsurpassed for brilliancy; easily raised from seed sown in spring. Height, 11/2 ft. The hardy, shrubby kinds may be increased by cuttings placed under glass. A mixture of loam and peat makes a fine soil for the greenhouse and frame varieties. They flower from March to July.

Lippia Reptans.–A frame creeping perennial which flowers in June. It requires a light soil. Cuttings of the young wood may be struck under glass. Height, 1 ft.

Lithospermum Prostratum.–A hardy perennial, evergreen trailer, needing no special culture, and adapting itself to any soil. It is increased by cuttings of the previous year’s growth, placed in peat and silver sand, shaded and kept cool, but not too wet. They should be struck early in summer, so as to be well rooted before winter sets in. Its blue flowers are produced in June. Height, 1 ft.

Loasa.–The flowers are both beautiful and curiously formed, but the plants have a stinging property. They grow well in any loamy soil, and are easily increased by seed sown in spring. Flowers are produced in June and July. Height, 2 ft. Besides the annuals there is a half-hardy climber, L. Aurantiaca, bearing orange-coloured flowers, and attaining the height of 10 or 12 ft.

Lobelia.–These effective plants may be raised from seed sown in January or February in fine soil. Sprinkle a little silver sand or very fine mould over the seed; place in a greenhouse, or in a frame having a slight bottom-heat, and when large enough prick them out about 1 in. apart; afterwards put each single plant in a thumb-pot, and plant out at the end of May. As the different varieties do not always come true from seed, it is best to propagate by means of cuttings taken in autumn, or take up the old plants before the frost gets to them, remove all the young shoots (those at the base of the plant are best, and if they have a little root attached to them so much the better), and plant them thinly in well-drained, shallow pans of leaf-mould and sand; plunge the pans in a hotbed under a frame, shade them from hot sunshine, and when they are rooted remove them to the greenhouse till spring, at which time growth must be encouraged by giving a higher temperature and frequent syringing. They may then be planted out in light, rich soil, where they will bloom in June or July. Height, 4 in.

Lobels Catchfly.–_See_ “Silene.”

London Pride.–_See_ “Saxifrage.”

Lonicera.–Hardy deciduous shrubs, which will grow in any ordinary soil, and produce their flowers in April or May. They are propagated by cuttings planted in a sheltered position. Prune as soon as flowering is over. Height, from 3 ft. to 10 ft.

Lophospermum.–Very elegant half-hardy climbers. Planted against a wall in the open air, or at the bottom of trellis-work, they will flower abundantly in June, but the protection of a greenhouse is necessary in winter. They like a rich, light soil, and may be grown from seeds sown on a slight hotbed in spring, or from cuttings taken young and placed under glass. Height, 10 ft.

Love Apples.–_See_ “Tomatoes.”

Love Grass.–_See_ “Eragrostis.”

Love-in-a-Mist.–_See_ “Nigella.”

Love-lies-Bleeding (_Amaranthus Caudatus_).–A hardy annual bearing graceful drooping racemes of crimson blossom. The seed should be sown in the open at the end of March, and thinned out or transplanted with a good ball of earth. Makes a fine border plant. Height, 2 ft.

Luculia Gratissima.–A fine plant either for the wall or border. It grows well in a compost of peat and light, turfy loam, but it is not suitable for pot culture. During growing time abundance of water is needed. When flowering has ceased, cut it hard back. It may be increased by layering, or by cuttings placed in sand under glass and subjected to heat. It flowers in August. Height, 8 ft.

Lunaria.–_See_ “Honesty.”

Lupins.–Though old-fashioned flowers, these still rank among our most beautiful annual and herbaceous border plants. They may be grown in any soil, but a rich loam suits them best. The seed germinates freely when sown in March, and the flowers are produced in July. Height, 2 ft. to 3 ft.

Lychnis.–Hardy perennials which, though rather straggling, deserve to be cultivated on account of the brilliancy of their flowers. L. Chalcedonica, commonly known as Ragged Robin, is perhaps the most showy variety; but L. Viscaria Plena, or Catchfly, is a very beautiful plant. They grow freely in light, rich, loamy soil, but need dividing frequently to prevent them dwindling away. The best season for this operation is early in spring. Beyond the care that is needed to prevent the double varieties reverting to a single state, they merely require the same treatment as other hardy perennials. They flower in June and July. Height, 2 ft. to 3 ft.

Lyre Flower.–_See_ “Dielytra.”

Lysimachia Clethroides.–This hardy perennial has something of the appearance of a tall Speedwell. When in flower it is attractive, and as it blooms from July on to September it is worth a place in the border. A deep, rich loam is most suitable for its growth, and a sheltered position is of advantage. The roots may be divided either in November or early in spring. Height, 3 ft.

Lysimachia Nummularia (_Creeping Jenny_).–This plant is extremely hardy, and is eminently suitable either for rock-work or pots. It is of the easiest cultivation, and when once established requires merely to be kept in check. Every little piece of the creeping root will, if taken off, make a fresh plant.

Lythrum.–Very handsome hardy perennials which thrive in any garden soil, and may be raised from seed or increased by dividing the roots. They flower in July. Height, of different varieties, 6 in. to 4 ft.

M

Madia.–A hardy annual of a rather handsome order. The seed should be sown in May in a shady situation. The plant is not particular as to soil, and will flower about eight weeks after it is sown, and continue to bloom during August and September. Height, 11/2 ft.

Magnolia Grandiflora.–A handsome, hardy evergreen, with large shining, Laurel-shaped leaves, and highly-scented, Tulip-shaped white flowers. A noble plant for a spacious frontage, but in most places requires to be grown on a wall. It flourishes in any damp soil, and is increased by layers. Flowers in August. Height, 20 ft.

Mahonia.–Handsome evergreen shrubs, useful for covert planting or for grouping with others. They grow best in a compost of sand, peat, and loam, and may be propagated by cuttings or by layers of ripened wood, laid down in autumn. They flower in April. Height, 4 ft. to 6 ft.

Maianthemum Bifolium.–The flowers of this hardy perennial are produced in April and May, and somewhat resemble miniature Lily of the Valley. Seed may be sown at the end of July. The plant will grow in any soil, but delights in partial shade. Height, 6 in.

Maize.–_See_ “Zea.”

Malope.–Very beautiful hardy annuals having soft leaves. They may be raised from seed sown in April in any garden soil. They bloom in June or July. Height, 11/2 ft. to 2 ft.

Malva.–Very ornamental plants, more especially the greenhouse varieties. The hardy perennials succeed in any good garden soil, and are increased by seed sown in the autumn, or by division of the root. The greenhouse kinds should be grown in rich earth: these are propagated by cuttings planted in light soil. The annuals are poor plants. Some of the varieties bloom in June, others in August. Height, 2 ft.

Mandevillea Suaveolens.–A fine climbing plant bearing very sweet white flowers in June. It is rather tender, and more suitable for the conservatory than the open air. It does not make a good pot-plant, but finds a suitable home in the border of the conservatory in equal parts of peat and sandy loam. In pruning adopt the same method as for the vine or other plants which bear flowers on wood of the same year’s growth. It is propagated by seed sown in heat, or by cuttings under glass. Syringe the leaves daily during the hot season. A temperature of from 40 to 50 degrees in winter, and from 55 to 65 degrees in summer should be maintained. Height, 10 ft.

Manures.–One of the best fertilisers of the soil is made by saturating charred wood with urine. This may be drilled in with seeds in a dry state. For old gardens liquid manure is preferable to stable manure, and if lime or chalk be added it will keep in good heart for years without becoming too rich. A good manure is made by mixing 64 bushels of lime with 2 cwts. of salt. This is sufficient for one acre. It should be forked in directly it is put upon the ground. Superphosphate of lime mixed with a small amount of nitrate of soda and forked into the ground is also a fine manure, but is more expensive than that made from lime and salt. Charred cow-dung is ready for immediate use. For established fruit-trees use, in showery weather, equal quantities of muriate of potash and nitrate of soda, scattering 1 oz. to the square yard round the roots. Peruvian guano, in the proportion of 1 oz. to each gallon of water, is a very powerful and rapid fertiliser. In whatever form manure is given, whether in a dry or liquid form, care must be taken not to administer it in excessive quantities, for too strong a stimulant is as injurious as none at all. In ordinary cases loam with a fourth part leaf-mould is strong enough for potting purposes; and no liquid except plain water should be given until the plants have been established some time. For roses, rhubarb, and plants that have occupied the same ground for a considerable time, mix 1 lb. of superphosphate of lime with 1/2 lb. of guano and 20 gallons of water, and pour 2 or 3 gallons round each root every third day while the plants are in vigorous growth. Herbaceous plants are better without manure. Liquid manure should be of the same colour as light ale.

Maple.–_See_ “Acer.”

Marguerites (_Chrysanthemums Frutescens_).–The White Paris Daisies are very effective when placed against scarlet Geraniums or other brightly-coloured flowers, and likewise make fine pot-plants. They will grow in any light soil, and merely require the same treatment as other half-hardy perennials. Height, 1 ft. (_See also_ “Anthemis” _and_ “Buphthalmum.”)

Margyricarpus Setosus (_Bristly Pearl Fruit_).–A charming little evergreen, of procumbent growth, bearing throughout the whole summer a number of berries on the main branches. Being only half-hardy, it requires protection from frost, but in the warmer weather it may be planted on rock-work in sandy loam and vegetable mould. Cuttings planted in moist peat under a hand-glass will strike, or it may be propagated by layers. Height, 6 in.

Marigolds.–Handsome and free-flowering half-hardy annuals. The greenhouse varieties thrive in a mixture of loam and peat, and cuttings root easily if planted in sand under glass. The African and tall French varieties make a fine display when planted in shrubberies or large beds, while the dwarf French kinds are very effective in the foreground of taller plants, or in beds by themselves. They are raised from seed sown in a slight heat in March, and planted out at the end of May in any good soil. Height, 6 in. to 2 ft. (_See also_ “Calendula,” “Tagetes,” _and_ “Calthus.”)

Martynia.–Handsome half-hardy, fragrant annuals. The seed should be sown on a hotbed in March. When the plants are sufficiently advanced transplant them singly into pots of light, rich earth, and keep them in the stove or greenhouse, where they will flower in June. Height, 11/2 ft.

Marvel of Peru (_Mirabilis_).–Half-hardy perennials, which are very handsome when in flower, and adorn equally the greenhouse or the open. They may be increased by seed sown in light soil in July or August and planted out in the border in spring. At the approach of frost take the roots up and store them in dry ashes or sand. They flower in July. Height, 2 ft.

Massonia.–Singular plants, which to grow to perfection should be placed in a mixture of loam, peat, and sand. They require no water while in a dormant state, and may be increased by seed or by off-sets from the bulbs. Height, 3 in. to 6 in.

Mathiola.–_See_ “Stocks.”

Mathiola Bicornis (_Night-scented Stocks_).–A favourite hardy annual whose lilac flowers are fragrant towards evening. They may be grown from seed sown between February and May on any ordinary soil. Height, 1 ft.

Matricaria.–This is a half-hardy annual of little interest so far as its flowers are concerned, and is mostly grown as a foliage plant. The seed should be sown in a frame in March, and transplanted at the end of May. Height, 1 ft.

Maurandia Barclayana.–This elegant twining plant is best grown in pots, so that it can more conveniently be taken indoors in the winter. The soil should be light and rich. Cuttings can be taken either in spring or autumn, or it may be raised from seed. It does very well in the open during the summer, placed against a wall or trellis-work, but will not stand the cold. In the greenhouse it reaches perfection, and blooms in July. Height, 10 ft.

Mazus Pumilio.–A pretty diminutive herbaceous plant. When grown in peat and sand in an open situation it survives from year to year, but it will not live through the winter in cold clay soils. Its pale green foliage is seen to advantage in carpet bedding, and its branched violet flowers, put forth from June to September, make it a desirable rock-work plant. It may be increased by transplanting, at the end of April, the rooted stems which run under the surface of the ground.

Meconopsis Cambrica(_Welsh Poppy_).–An ornamental hardy perennial, often found on English rocks. It may be grown in any light, rich soil, is easily raised from seed, and blooms in June. Height, 1-1/2 ft.

Medlars.–These trees will grow on any well-drained soil. The Dutch Medlar is most prized, as it bears the largest fruit. It is raised from seed, and usually trained to a standard form. The Nottingham and Royal are also excellent varieties. Any special variety may be grafted on to the seedlings. On deep soils it is best grafted on the Pear stock; on light, sandy soil it may be grafted on the White Thorn. No pruning is required, beyond cutting away cross-growing branches.

Megasea.–This hardy herbaceous plant flowers from April to June. A light, sandy soil suits it best. It may be grown from seed or multiplied by division. Height, 1 ft.

Melissa Officinalis.–A hardy perennial, flowering in July. Any soil suits it. It is increased by division of the root. Height, 1 ft.

Melittis Melissophyllum (_Large-flowered Bastard Balm_).–This handsome perennial is not often seen, but it deserves to be more generally grown, especially as it will thrive in almost any soil; but to grow it to perfection, it should be planted in rich loam. It flowers from June to August, and may be increased by division of the roots any time after the latter month. Height, 11/2 ft.

Melon.–Sow from January to June in pots plunged in a hotbed, the temperature of which should not be under 80 degrees. When the plants have made four or five leaves, set them out in a house or hotbed having a temperature ranging from 75 to 85 degrees. Keep the plants well thinned and water carefully, as they are liable to damp off at the collar if they have too much wet. Do not allow them to ramble after the fruit has begun to swell, nor allow the plants to bear more than two, or at most three, melons each. They require a strong, fibry, loamy soil, with a little rotten manure worked in. The Hero of Lockinge is a grand white-fleshed variety, and Blenheim Orange is a handsome scarlet-fleshed sort.

Menispermum Canadense (_Moon seed_).–A pretty slender-branched, hardy, climbing, deciduous shrub, with yellow flowers in June, followed with black berries. It grows in any soil, and can be propagated by seed, by division of roots, or by planting cuttings in spring in a sheltered spot. Height, 10 ft.

Mentha Rotundifloria Variegata (_Variegated Mint_).–A hardy perennial, which may be grown in any soil, and is easily increased by dividing the roots. It flowers in July. Height, 2 ft.

Menyanthes.–Treat as other hardy aquatics.

Menziesia (_Irish Heath_).–This evergreen thrives best in fibrous peat to which a fair quantity of silver sand has been added. While excessive moisture is injurious, the plant must not be kept too dry; the best condition for it is to be constantly damp. Slips torn off close to the stem will root in sand under glass, placed in gentle heat. Height, 2 ft.

Mertensia.–These hardy perennials flower from March to July. They will grow in any garden soil, but do best in peat, and are propagated by division. They make fine border plants. Mertensia Maritima and M. Parviflora, however, are best grown in pots, in very sandy soil, perfection being afforded them during the winter. Height, 11/2 ft. to 2 ft.

Mesembryanthemums (_Ice Plants_).–These half-hardy, annual succulents have a bright green foliage covered with ice-like globules. They must be raised in a greenhouse or on a hotbed, sowing the seed in April on sandy soil. Prick the young plants out in May. If grown in pots they thrive best in a light, sandy loam. In the border they should occupy a hot and dry situation. Keep the plants well watered until established, afterwards give a little liquid manure. May be increased by cuttings taken in autumn. Cuttings of the more succulent kinds should be allowed to dry a little after planting before giving them water. A dry pit or frame is sufficient protection in the winter; they merely require to be kept from frost. Flower in July. Height, 1 ft.

Mespilus.–_For treatment, see_ “Medlars.”

Meum Athamanticum.–A hardy perennial with graceful, feathery green foliage, but of no special beauty. It is a native of our shores, will grow in any soil, blooms in July or August, and is freely propagated by seeds. Height, 1-1/2 ft.

Michaelmas Daisies (_Starworts_).–A numerous family of hardy herbaceous perennials. Some few are very pretty, while others can only be ranked with wild flowers. They thrive in any soil or position, but flourish best where there is a due proportion of sunshine. They are easily raised from seed, sown early in spring, or may be increased by root-division either in the autumn, as soon as they have done flowering, or in the spring. They vary in height from 1 ft. to 5 ft.

Michauxia Campanuloides.–This is an attractive border biennial, bearing from March to June white campanula-like flowers tinged with purple, on erect stems. It is not particular as to soil, but requires a southern position and protection in winter. Propagated by seeds in the same way as other biennials. Height, 4 ft.

Mignonette.–For summer-flowering plants sow the seed in spring, and thin out to a distance of 9 in. apart. To obtain bloom during the winter and spring successive sowings are necessary. Let the first of these be made the second week in July in light, rich soil; pot off before frost sets in, plunge them in old tan or ashes, and cover with a frame facing the west. Another sowing should be made about the middle of August, giving them the same treatment as the previous; and a third one in February, in gentle heat. Height, 9 in. to 3 ft. The Mignonette tree is produced by taking a vigorous plant of the spring sowing, and removing all the lower shoots in the autumn. Pot it in good loam, and keep it in the greenhouse in a growing state, but removing all the flowers. By the spring the stem will be woody. Let the same treatment be given it the second year, and the third season it will have become a fine shrub. It may be made to bloom during the winter by picking off the blossom in the summer and autumn. Height, 3 ft.

Mildew.–Syringe with a strong decoction of green leaves and tender branches of the elder-tree, or with a solution of nitre made in the proportion of 1 oz. of nitre to each gallon of water. Another good remedy is to scatter sulphur over the leaves while the dew is upon them, afterwards giving them a syringing of clear water.

Milkmaid.–_See_ “Cardamine.”

Milk Thistle.–_See_ “Carduus.”

Mimosa.–These shrubs are often called Sensitive Plants, on account of the leaves of several of the species of this genus shrinking when touched. They grow well in loam and peat with a little sand, but require to be planted in a warm situation or to have greenhouse care. Cuttings of the young wood root readily in sand under a glass. They may also be raised from seed. Mimosa Pudica exhibits most sensibility. Height, 2 ft.

Mimulus (_Monkey Flower_).–Showy half-hardy perennials which thrive in moist and shady situations and in almost any soil. They may be grown from seed sown in slight heat from February to May, or increased by division of the root. The frame and greenhouse kinds grow best in a rich, light soil, and may be multiplied by cuttings. The annuals may be sown where they are to flower. They bloom in June and July. Height, 2 in. to 11/2 ft. (_See also_ “Diplacus.”)

Mina Lobata.–A charming half-hardy annual climber, bearing singularly shaped flowers, produced on long racemes. When young the buds are a vivid red, changing to orange-yellow, and when fully expanded the flowers are creamy-white. It thrives in loam and peat to which a little dung has been added, and is well adapted for arbours, trellises, or stumps of trees. Sow the seed on a hotbed in March, harden off, and transplant when all fear of frost is over. Height, 8 ft. to 12 ft.

Mint.–May be grown in any garden soil. It is increased by runners, which, if not held in check, become very troublesome. The roots may be confined by means of tiles or slates. Flowers in July. Height, 11/2 ft.

Mistletoe.–Raise the bark of an apple, pear, or oak tree on the underneath part of a branch and insert some well-ripened berries, then tie the bark down neatly with raffia or woollen yarn. If the berries were inserted on the top of the branch the operation would result in failure, as the birds would devour them.

Mitella Diphylla.–A hardy perennial which bears slender racemes of white flowers in April. It makes a pretty rock plant, delights in a peat soil, and is increased by division of the root. Height, 6 in.

Moles.–These pests may be destroyed by placing in their runs worms that have been kept for some time in mould to which carbonate of barytes has been added.

Monardia Didyma (_Oswego Mint, or Horse Balm_).–_See_ “Bergamot.”

Monetia Barlerioides.–An ornamental shrub, suitable for the greenhouse or stove. It requires to be grown in loam and peat, and may be increased by cuttings planted in sand, under glass, in a bottom-heat. Height, 3 ft.

Monkey Flower.–_See_ “Mimulus.”

Monkey Puzzle.–_See_ “Araucaria.”

Monk’s-hood.–_See_ “Aconite.”

Montbretia.–Very graceful and showy plants. The flowers, which are like small Gladioli, are produced on long branched spikes and are excellent for cutting. Plant 3 in. deep and 2 in. apart in sandy loam and leaf-mould. The corms should never be kept long out of the ground, as they shrivel, and weak growth and few flowers are the result. Though they are hardy it is well to give them a covering of litter in winter. They may also be grown in pots. Height, 2-1/2 ft.

Moraea Iridioides.–These plants flower in May, and require the same treatment as Ixias.

Morina (_Whorl Flower_).–An ornamental hardy perennial, which is seldom met with. It forms rosettes of large, deep green, shiny foliage and stout spikes of rose-coloured flowers in whorls, which make it one of the most attractive of Thistles. It likes a rich, light soil, is increased by seed sown in the autumn, also by division in August, and flowers in July. Height, 21/2 ft.

Morisia Hypogaea.–This is a pretty hardy perennial for rock-work. It flowers in May, and is raised from seed sown as soon as it is ripe. Height, 2 in.

Morna Elegans.–Beautiful half-hardy annuals. For early flowering sow the seed in September: for later blooms sow in February in slight heat, pot off, affording good drainage to the plants. They are very sensitive to cold, and should not be placed out of doors before the end of May. Avoid over-watering, as this would prove fatal to them. The soil should be light and sandy. Those sown in September will bloom in the greenhouse in May; those sown in February will flower in the open in the autumn. Height, 11/2 ft.

Morning Glory.–_See_ “Convolvulus.”

Morrenia Odorata.–A good twining plant for the greenhouse, producing fragrant cream-coloured flowers in July. It will grow in any good loamy soil, and may be increased by cuttings. Height, 3 ft.

Moss.–To eradicate moss from fruit-trees wash the branches with strong brine or lime water. If it makes its appearance on the lawn, the first thing to do is to ensure a good drainage to the ground, rake the moss out, and apply nitrate of soda at the rate of 1 cwt. to the half-acre, then go over the grass with a heavy roller. Should moss give trouble by growing on gravel paths, sprinkle the ground with salt in damp weather.

Mountain _Avens.–See_ “Dryas.”

Muhlenbeckia Complexa.–A very decorative climber, hardy in nature but requiring a good amount of sunshine to make it bloom. A well-drained, sandy soil is best for its growth, and it can be increased by cuttings of hardy shoots taken early in summer. Height, 6 ft.

Mulberries.–Any good soil will grow the Mulberry. The tree is hardy, but the fruit wants plenty of sunshine to bring it to perfection. It may be propagated by cuttings of wood one year old with a heel two years old attached. The only pruning necessary is to keep the branches well balanced. Autumn is the time to do this, not forgetting that the fruit is borne on the young wood. When grown in tubs or large pots in the greenhouse the fruit attains the perfection of flavour. In addition to the Large Black and the White (Morus Alba) the New Weeping Russian White may be recommended.

Mulching.–_See_ “Soil.”

Muscari.–_See_ “Hyacinthus.”

Muscari Botryoides.–_See_ “Hyacinthus.”

Mushrooms.–Take partially dry horse manure and lay it in a heap to ferment. Turn and mix it well every few days, and when well and equally fermented, which will be from ten to fourteen days, make it into a bed 4 ft. wide and 2 ft. deep, mixing it well together and beating or treading it firmly. When the temperature of the bed falls to 75 degrees, or a little under, the spawn may be inserted in pieces about the size of a walnut, 2 in. deep and 6 in. apart. Now give a covering of loamy soil, 2 in. deep, and beat it down evenly and firmly. Finish off with a covering of clean straw or hay about 1 ft. thick. Water when necessary with lukewarm water; but very little should be given till the Mushrooms begin to come up, then a plentiful supply may be given. They may be grown in any warm cellar or shed, and usually appear in from four to six weeks after planting.

Musk (_Mimulus Moschatus_).–A well-known sweet-scented, half-hardy perennial, well adapted for pot culture. A moist, shady position is most congenial to it when placed in the border. Seed sown in autumn make fine, early-flowering greenhouse plants. For summer blooming the seed is sown early in spring, under a frame or hand-glass, at a temperature of from 55 to 60 degrees. It is readily propagated by division. Height, 6 in.

Mustard and Cress.–For sowing in the open choose a shady border, make the surface fine and firm, and water it well before putting down the seed. Let the seed be sown thickly at intervals of seven or fourteen days from March to September. As the Cress does not germinate so quickly as the Mustard, the former should be sown four days before the latter. The seed must not be covered, but simply pressed into the surface of the soil. Keep the ground moist, and cut the crop when the second leaf appears. For winter use it is best sown in boxes and grown in a frame, the seed being covered with flannel kept constantly moist. This may be removed as soon as the seed germinates. Gardeners mostly prefer to grow it through coarse flannel, to avoid the possibility of grit being sent to table. The curled leaf Cress is the best, and the new Chinese Mustard is larger in leaf than the old variety, and is very pungent in flavour.

Myosotis (_Forget-me-not_).–The perennial varieties of these beautiful plants grow best in moist places, such as the edges of ponds or ditches; but they also do well in pots among Alpine plants. Most of them may be increased by root division, and all of them by seed. The annuals like a dry, sandy soil, and are grown from seed sown in March. They flower in June or July. Height, 6 in.

Myrica Gala (_Candleberry Myrtle_).–This hardy deciduous shrub is very ornamental, and its foliage is scented like the myrtle. It will grow in light, rich soil, but thrives best in peat, and may be increased by seeds or layers. May is its flowering time. Height, 4 ft. M. Cerifera is treated in precisely the same manner. Height, 6 ft.

Myrsiphyllum Asparagoides.–_See_ “Smilax.”

Myrtle (_Myrtus_).–Will strike readily if the cuttings be placed in a bottle of water till roots grow, and then planted; or young cuttings will strike in sandy soil under a hand-glass. They succeed best in a mixture of sandy loam and peat and on a south wall. Near the sea they prove quite hardy. Height, 6 ft.

N

Narcissus.–_See_ “Daffodils.”

Nasturtiums.–These are among the most useful of our hardy annuals, producing a display of the brightest of colours throughout the entire summer. The tall-growing climbers make a gay background to a border, and are equally valuable for trellis-work, while the dwarf varieties are first-class bedding plants, and of great service for ribboning. The seeds may be sown in pots in September or in the open ground early in spring. A light sandy or gravelly soil is the best to produce a wealth of bloom. Height, 6 ft. and 1 ft.

Nectarines.–Require the same treatment as the Peach. In fact, the Nectarine stone sometimes produces a Peach, and a Peach stone often produces a Nectarine. Fairchild’s, Humboldt, Lord Napier, and Red Roman are useful varieties. They should stand 20 ft. apart.

Neilla.–These shrubs thrive in ordinary soil, and are increased by cuttings of the young wood. They flower in July. N. Torreyi bears white Spiraea-like flowers, which are very effective. Height, 6 ft.

Nemesia.–A most beautiful half-hardy annual of the Antirrhinum class. Sow the seed early in spring on a hotbed, and plant out in May in rich, light soil. Cuttings of the young wood will strike under glass. Height, 1-1/2 ft. to 2-1/2 ft.

Nemophila.–Pretty, neat, and compact hardy annuals, well worth cultivating. They succeed best in a moist and shady situation, delight in peat or vegetable mould, and when grown in circles are very striking. If wanted to flower early, sow the seed in autumn, or on a hotbed in spring; and if required for late blooming, sow in the open in March. Treated thus they flower from June to September. Height, 1 ft.

Nepeta Glechoma Variegata.–A very useful plant for hanging baskets. It can be trained as a pyramid or allowed to hang down; in many cases it is employed as edgings. It is of easy culture, and does well as a window plant or in a cool greenhouse. The soil should be light and dry. It flowers in July, and may be increased by root-division.

Nerine Sarniense.–_See_ “Guernsey Lily.”

Nertera Depressa (_Coral Berry_).–This pretty Moss-like plant is fairly hardy, and is eminently suited for a sheltered position on the rockery. The soil should consist of leaf-mould and sand, and overhead sprinkling with soft water is very beneficial. In cold districts it is better to grow it in the greenhouse. The flowers are produced in July, succeeded by orange-coloured berries. It is easily increased by dividing it early in the spring. Height, 3 in.

Neuvusia Alabamensis.–A tamarix-like shrub, bearing clusters of white flowers early in spring. Will grow in any soil or situation. Increased by cuttings placed in sand under glass.

Nicotiana (_Tobacco Plants_).–Very showy half-hardy annuals. N. Affinis bears long, tubular, sweet-scented, white flowers in July, and grows to the height of 3 ft. N. Virginica produces immense leaves and pink flowers, and the plants are 4 to 5 ft. high. The seed is sown on a hotbed in spring, and when the second or third leaf appears the plants are put into small pots and placed in a frame till the end of May, when they are transferred to the border.

Nierembergia (_Cup Flowers_).–These elegant half-hardy annuals grow well in any light soil, but prefer a mixture of sandy loam and leaf-mould. Sow the seed in March or April in slight heat, harden off, and plant out in May as soon as all fear of frost is over. They flower in July. Height, 9 in. to 1 ft.

Nierembergia Rivularis.–This herbaceous plant is of a creeping nature; it has deep green ovate foliage and large saucer-shaped white flowers. It needs a moist position, and is increased by division. The bloom is produced throughout June, July, and August. Height, 3 in.

Nigella.–These hardy annuals, a species of Fennel-flower, are both curious and ornamental. Perhaps the best known among them is N. Hispanica, or Love-in-a-Mist. They only require sowing in the open in spring–but not before the middle of March–to produce flowers in July and August. Height, 9 in. to 2 ft.

Night-scented Stocks.–_See_ “Mathiola.”

Nolana.–Hardy annuals that are suitable for the border, as they are very showy when in flower. The seed should be sown in spring on a gentle hotbed, and the plants transferred to the garden about the middle of May. N. Atriplicifolia may be sown in the open in the autumn. They flower in July and August. Height, 6 in. to 2 ft.

North Borders, Plants suitable for.–Hardy Camellias, Chrysanthemums, black and green Tea Plant, Rhododendrons, Ferns, Red Currants, Morello Cherries, and spring and summer cuttings of all sorts.

Nuttallia.–This early-flowering shrub is only hardy in the south and south-west of our country. It requires a light, rich soil, and may be increased by division. Racemes of white flowers are produced during February and March. Height, 2 ft.

Nycterina.–Exquisite little half-hardy plants, suitable for pots or rock-work. The seed should be sown early in spring on a gentle hotbed, and the young plants transferred to the pots or open ground at the end of May, using a light, rich soil. Height, 3 in.

Nymphaea Alba.–A hardy aquatic perennial, frequently found in our ponds. It flowers in June, and may be increased by dividing the roots. Height, 1 ft.

O

Odontoglossum Grande.–A most beautiful orchid, delighting in a temperature of from 60 to 70 degrees and an abundance of water during summer, but good drainage is essential. The blooms are yellow, spotted and streaked with venetian red, and are often 6 in. across. The pots should be two-thirds filled with crocks, then filled up with fibrous peat and sphagnum moss. During winter only a very little moisture should be given.

Oenothera.–The Evening Primroses are most useful and beautiful plants, well suited for ornamenting borders, beds, edgings, or rock-work. All the species are free-flowering, and grow well in any good, rich soil. The annual and biennial kinds are sown in the open in spring. The perennials may be increased by dividing the roots, by cuttings, or by seed, the plants from which will flower the first season if sown early in spring. They bloom in June and July. Height, 6 in. to 4 ft.

Olearia.–These evergreen shrubs thrive in peat and loam, and may be increased by division of the roots. O. Haastii has foliage resembling the Box, and a profusion of white, sweet-scented flowers in summer: a chalk soil suits it admirably. Height, 3 ft. to 4 ft.

Omphalodes Verna.–A hardy perennial which may be grown under the shade of trees in ordinary soil. It produces its flowers in March, and is increased by dividing the roots in autumn. Height, 6 in.

Oncidium Sarcodes.–Plant these Orchids firmly in well-drained pots, using equal parts of live sphagnum and fibrous peat. Give one good watering as soon as the potting is finished, and stand them in a light, warm part of the greenhouse. They will require very little more water until the roots have taken hold of the soil–only sufficient to keep the pseudo-bulbs from shrivelling–and during the winter months scarcely any moisture is needed. They flower in August. Height, 1-1/2 ft.

Onions.–Require a deep, rich, heavy soil. Where the ground is not suitable it should have had a good dressing of rotten manure the previous autumn, and left in ridges during the winter. Level the ground, and make it very firm just before the time of sowing. The seed should be sown early in March for the main crop and for salad and pickling Onions, and in August for summer use. Thin out to about 6 in. apart, excepting those intended to be gathered while small. The Tripoli varieties attain a large size if transplanted in the spring. The Silver-skins do best on a poor soil. For exhibition Onions sow in boxes early in February in a greenhouse; when about 1 in. high prick out, 3 in. apart, into other boxes; give gentle heat and plenty of air, and when they have grown 6 in. high put them in a cool frame until the middle of April, when they must be planted in the open, 1 ft. apart.

Ononis Rotundifolia (_Round-leaved Restharrow_).–A charming hardy evergreen of a shrubby nature. It will grow in any ordinary garden soil, and is increased by seed, sown as soon as it is ripe. It is most effective in clumps, and blooms from June to September. Height, 1-1/2 ft.

Onopordon.–Half-hardy perennials of a rather interesting nature and of easy cultivation. Sow the seed any time between March and June. They require the protection of a frame or greenhouse during winter, and produce flowers in July. Height, 6 in. to 8 ft.

Onosma Taurica (_Golden Drop_).–This hardy herbaceous plant is very pretty when in flower, and suitable for rock-work. It requires a well-drained vegetable mould, and to be planted where it can obtain plenty of sun. It is increased from cuttings taken in summer, placed in a cucumber frame, kept shaded for about a fortnight, and hardened off before the winter. The flowers succeed one another from June to November. Height, 1 ft.

Opuntia Rafinesquii (_Hardy Prickly Fig_).–A dwarf hardy Cactus with sulphur-coloured flowers, produced from June to August; very suitable for dry spots in rock-work. It grows best in peat with a little sand, and is propagated by separating the branches at a joint, and allowing them to dry for a day or so before putting them into the soil. Height, 2 ft.

Orange, Mexican.–_See_ “Choisya.”

Orchids.–The four classes into which these charming and interesting plants are divided may be described as (1) those coming from the tropics, (2) from South Africa, (3) from the South of Europe, and (4) our native varieties. The first require a stove, the second a greenhouse, the third and fourth slight protection during winter. As their natural character differs so widely it is necessary to ascertain from what part of the globe they come, and to place them in houses having as near as possible the same temperature and humidity as that to which they are accustomed. The pots in which they are grown should be filled with fibrous peat and sphagnum moss, largely mixed with charcoal, and abundant drainage ensured. They are propagated by dividing the root stocks, by separating the pseudo-bulbs, and, in case of the Dendrobiums, by cuttings. Orchis Foliosa (_Leafy Orchis_) may be grown in the open ground in good sandy loam. When once established it is best not to disturb it, but if needed it may be increased by division, after the tops have died down. Orchis Fusca (_Brown Orchis_) may likewise be planted in the open, in a sheltered position, in fine loam and leaf-mould, the soil to be well drained, yet constantly moist.

Origanum Pulchellum.–Popularly known as the Beautiful Marjoram, this plant is useful for cutting for vases. It is perennial and hardy, and thrives in a dry situation with a sunny aspect and in a sandy soil. The bloom is in its best condition in October. The rooted shoots may be divided in spring or almost at any other period, or it may be propagated by taking cuttings in summer. Height, 1-1/2 ft.

Ornithogalum.–O. Arabicum bears a large white flower with a shiny black centre. It is a fine plant for pot culture, or it may be grown in water like the Hyacinth. It may be planted in the open early in spring in sandy loam and peat. Take it up before the frost sets in and store it in a dry place, as it requires no moisture while in a dormant state. In September the flowers are produced. Height, 6 in. O. Umbellatum (_Star of Bethlehem_) is a pretty little flower often found in English meadows, is quite hardy, and once established may be left undisturbed for years. It throws up large heads of starry flowers, which are produced in great abundance. While in a dormant state the bulbs should be kept almost dry. It is propagated by off-sets; flowers in May. Height, 1 ft.

Orobus.–These hardy perennials bear elegant Pea-shaped blossoms. The plants will grow readily in any light soil, and are easily increased by root-division in the spring, or by seeds. They flower in June. Height, 2 ft. to 3 ft.

Osmanthus.–These elegant hardy evergreen shrubs succeed best in light, sandy loam, and like a dry situation. They may be increased by cuttings of the young shoots with a little old wood attached, or they may be grafted on to common Privet. The variegated varieties are very beautiful. They grow well on chalk soils. Height, 4 ft. to 6 ft.

Othera Japonica.–A newly introduced evergreen shrub very similar to the Holly. It is perfectly hardy and may be treated in the same manner as that plant.

Ourisia Coccinea.–A hardy herbaceous, surface-creeping perennial of singular beauty as regards both leaf and flower. The soil in which it is grown must be well drained, a peat one being preferable; and the position it occupies must be well shaded from the rays of the midday sun. It flowers from May onwards to September, the cut bloom being admirable for mixing with fern leaves. As soon as new life starts in spring the roots may be divided. Height, 9 in.

Oxalis.–A genus of very pretty bulbous plants that thrive well in a mixture of loam, peat, and sand, or will grow in any light soil. Most of the tender kinds may be reared in a frame if protected from frost in the winter. After they have done flowering they should be kept dry until they begin to grow afresh. They are increased by off-sets from the bulb. The hardy species should be planted in a shady border, where they will grow and flower freely. The seeds of these may be sown in the open in spring. Some of the varieties have fibrous roots: these will bear dividing. They are equally suitable for pots, borders, or rock-work. Height, 9 in. to 3 ft.

Ox-Tongue.–_See_ “Bugloss.”

Oxythopis Campestris.–A hardy perennial with lemon-yellow flowers in June and July. It will grow in any good garden soil, and is propagated by seed only, which should be sown where the plants are intended to be grown. Height, 6 in.

P

Pachysandra.–This early hardy perennial has ornamental foliage and blooms in April. It will succeed in almost any soil, and may be increased by suckers from the roots. Height, 1 ft.

Paeonies.–These beautiful flowering plants are mostly hardy enough to endure our winters. The herbaceous kinds are increased by dividing the plants at the roots, leaving a bud on each slip. The shrubby species are multiplied by cuttings taken in August or September, with a piece of the old wood attached, and planted in a sheltered situation. Tree Paeonies require protection in winter, and may be propagated by grafting on to the others, by suckers, or by layers. New varieties are raised from seed. A rich, loamy soil suits them best. Height, 2 ft.

Palms from Seed.–Soak the seed in tepid water for twenty-four hours, then put them singly 1 in. deep in 2-in. pots filled with equal parts of loam, leaf-mould, and sand. Cover the pots with glass and stand them in the warmest part of a hothouse. Shade from strong sunshine, and keep the soil just moist. Re-pot as soon as the roots have filled the old ones.

Pampas Grass.–_See_ “Gynerium.”

Pampas Lily of the Valley.–_See_ “Withania.”

Pancratium.–A handsome class of plants. Their habit of growth is somewhat like that of the Amaryllis. They are admirably adapted for growing in pots in the greenhouse. They may also be planted in the open ground under a south wall. The bulbs should be placed in a composition of three parts light, sandy loam and one of vegetable mould. They are increased by off-sets from the roots, or by seeds, by which the new varieties are obtained. Height, 1 ft. to 2 ft.

Pandanus Veitchi (_Variegated Screw Pine_).–For table decoration or vases this is a most useful plant. It requires a warm greenhouse where a temperature of 60 or 70 degrees can be kept up throughout the year, and grows well in equal parts of peat and loam with one-sixth part sand. During the autumn a little liquid manure is beneficial. In the winter months it should be watered carefully, but in the summer it is improved by syringing with warm water. It is propagated very easily by suckers taken off in spring or summer, placed in a temperature of 75 degrees.

Panicum.–Handsome ornamental grasses. They will grow in any soil or situation. P. Capillare is an annual, suitable for bouquets or edgings; it is increased by seed. P. Altissimum, an annual, and P. Sulcatum, a most elegant greenhouse plant, are fine for specimens. P. Plicatum is highly ornamental and hardy, but is best grown as a conservatory or window plant; it has a Palm-like appearance, and is of quick growth. Most of the plants flower in July. They may be propagated by seed or by division of the roots. Average height, 1-1/2 ft.

Pansies (_Heartsease_).–Grow well from seed sown in July or August on a raised bed of light earth. They may also be increased from cuttings taken in August, September, April, or May, selecting young side-shoots and planting them in light earth mixed with silver sand. The cuttings should be kept in a cool frame, moderately moist, and shaded from the hot sun. They can likewise be increased by layers, merely pegging them down and not slitting them on account of their tendency to damp off. They may also be increased by dividing the roots in April or May. They should be planted where they will get all the morning sun, yet be sheltered from mid-day rays; in an open and airy situation, yet protected from cutting winds. While the plants are blooming they should be supplied with liquid manure.

Papaver (_Poppy_).–These showy flowers are most at home in a rich, light soil. They are easily raised from seed sown where they are intended to bloom. The perennials may also be increased by dividing the roots. They flower at midsummer. Height varies from 1 ft. to 3 ft.

Pardanthus Chinensis.–_See_ “Iris.”

Parsley.–In order to grow Parsley to perfection it is necessary that the ground be well drained, as the roots and stems must be kept dry, and the soil should be rich and light. Three sowings may be made during the year: the first in spring for late summer and autumn use, the next in June for succession, and another in August or September for spring and early summer use. Thin out or transplant, to 6 in. apart. Parsley takes longer than most seeds to germinate; it must therefore be watched during dry weather and watered if necessary. Plants potted in September and placed in a cold frame, or protected in the open from rain and frost with a covering of mats supported by arches, will be valuable for winter use.

Parsnips.–These succeed best in a rich soil, but the application of fresh manure should be avoided, as it induces forked and ill-shaped roots. Let the ground be trenched two spits deep and left ridged up as long as possible. As early in March as the weather will permit level the surface and sow the seed in drills 15 in. apart, covering it with half an inch of fine soil. When the plants are 2 or 3 in. high, thin them out to 9 in. apart. They may be taken up in November and, after cutting off the tops, stored in a pit or cellar in damp sand, or they may be left in the ground till required for use.

Passion Flower.–Cuttings of the young shoots strike readily in sand under glass. The plant likes a good loamy soil mixed with peat. A sheltered position with a south or south-western aspect should be assigned those grown out of doors, and the root should be well protected in winter. The flowers are borne on seasoned growth of the current year: this fact must be considered when pruning the plants. During the hot months the roots require a copious supply of water, and the foliage should be syringed freely. Passiflora Caerulea is fine for outdoor culture, and Countess Guiglini makes a capital greenhouse plant.

Pavia Macrostachya.–This is a deciduous hardy shrub or tree which bears elegant racemes of white Chestnut-like flowers in July. Any soil suits it. It is propagated by layers or by grafting it on to the Horse-chestnut. Height, 10 ft.

Peaches.–These are best grown on a strong loam mixed with old mortar; though any soil that is well drained will produce good fruit. When possible, a south wall should be chosen; but they are not particular as to position, providing they are afforded shelter from cold winds. November and February are the most favourable months for planting. The roots should be carefully arranged at equal distances apart, 3 or 4 in. below the surface of soil, and then covered with fine mould. Avoid giving manure at all times, except when the trees are bearing fruit heavily. Train the shoots about 6 in. apart, removing all the wood-buds except one at the base of the shoot and one at the point. Keep the flowers dry and free from frost by means of an overhead shelter, to which tiffany or canvas can be attached, which should, however, only be used so long as the cold weather lasts. To ensure good fruit, thin the same out to 6 in. apart as soon as it attains the size of a small pea, and when the stoning period is passed remove every alternate one, so that they will be 1 ft. apart. After gathering the fruit, remove any exhausted and weak wood, leaving all that is of the thickness of a black-lead pencil. To keep the foliage clean, syringe once a day with water; this may be continued until the fruit is nearly ripe. The following may be recommended for outdoor cultivation:–Hale’s Early, Dagmar, and Waterloo for fruiting in July or August; Crimson Galande, Dymond, and the well-known Bellegarde for succession in September; and Golden Eagle for a late sort. When planted in quantities, Peaches should stand 20 ft. apart.

When grown under glass a day temperature of 50 degrees, falling to 45 degrees at night, is sufficient to start with, gradually increasing it so that 65 degrees by day and 55 by night is reached at the period of blossoming. Syringe the leaves daily until the flowers are produced, then discontinue it, merely keeping the walls near the pipes and the paths damp. As soon as the fruit is set the syringing should recommence. Water of the same temperature as that of the house should in all cases be used. When the fruit begins to ripen, cease once more the syringing until it is gathered, then admit air freely, wash the trees daily, and apply liquid manure to the roots in sufficient quantities to keep the soil moist during the time the trees are at rest. Rivers’s Early, Pitmaston Orange, Dagmar, and Royal George are all good under glass.

Pears.–Wherever Apples are a success Pears will grow. As a rule, they are best grown dwarf. On light soils they should be grafted on to Pear stocks, but on heavy soils they are best worked on the Quince. The fruiting of young trees may be accelerated by lifting them when about five years old, spreading out the roots 1 ft. below the surface of the soil, and mulching the ground. The mulching should be raked off in the spring, the ground lightly stirred with a fork and left to sweeten, and another mulching applied when the weather becomes hot and dry. In pruning, leave the leading branches untouched, but let all cross shoots be removed, and the young wood be cut away in sufficient quantity to produce a well-balanced tree, and so equalise the flow of sap. Some of the pruning may be done in summer, but directly the leaves fall is the time to perform the main work. A good syringing once a week with the garden hose will keep the trees vigorous and free from insects. Should scab make its appearance on the leaves, spray them occasionally with Bordeaux Mixture, using the minimum strength at first, and a stronger application afterwards if necessary. There are over 500 varieties of Pears, so it is no easy matter to give a selection to suit all tastes, but a few may be named as most likely to give satisfaction. Louise Bonne de Jersey succeeds in almost any soil and in any situation, is a great favourite, and ripens its fruit in October. Beurre Giffard makes a fine standard, and ripens in July. Beurre Hardy is delicious in October and November. Doyenne du Comice is one of the best-flavoured, and is very prolific. Beurre d’Amanlis ripens in August. Williams’s Bon Chretien, Aston Town, Pitmaston Duchess, Clapp’s Favourite, Comte de Lamy, and Josephine de Malines are all reliable for dessert, while for stewing purposes Catillac, Black Pear of Worcester, Verulam, and Vicar of Winkfield are among the best. In orchards standards should be from 20 to 25 ft. apart; dwarfs 12 ft. to 1 rod.

Peas.–For the production of heavy summer and autumn crops a rich and deeply-stirred soil is essential, one of the best fertilisers being well-decayed farmyard manure; but for the earliest crop a poorer soil, if deep and well pulverised, will give the best results. Peas under 3 ft. in height do not require sticking, but they can be more easily gathered if a few small twigs are used to keep the haulm off the ground. If sown in successive lines the space between the rows should correspond with the height of the variety grown. A good plan is to arrange the rows 10 or 15 ft. apart, and crop the intervening spaces with early dwarf vegetables. The earliest varieties may be sown from November to February, on the warmest and most sheltered border: these may be gathered in May and June. The second early round, varieties, if sown from January to April, will be ready for gathering in June and July. The main crop round varieties may be sown from February to May: these will be ready to gather in July and August. The early wrinkled varieties may be sown from March to June, for gathering between June and September. Sow main crop and late varieties at intervals of fourteen days from March to May: these will be ready to gather in July, August, and September. When the plants are a couple of inches high draw the earth neatly round them, and stake the taller varieties as soon as the tendrils appear. Keep them well watered in dry weather, and if on a light soil a mulching of manure will be beneficial. As soon as the pods are setting apply weak liquid manure to the roots when the ground is moist.

Peas, Everlasting (_Lathyrus Latifolia_).–These well-known and favourite hardy perennials are very useful for covering trellises, etc. They will grow in any garden soil, and may be raised from seed sown early in spring in slight heat. Where there is no greenhouse or frame the seed may be planted, about 1/2 in. deep, round the edges of pots filled with nice, light soil, and covered with a sheet of glass, keeping the soil moist till the seed germinates. When the plants are strong enough they may be placed in their permanent quarters. They bloom from June to September. Old roots may be divided. Height, 6 ft.

Peas, Sweet.–These most beautiful and profuse blooming hardy annuals will grow almost anywhere, but they prefer a dry soil that is both rich and light. The seed should be sown as early in March as practicable, and in April and May for succession. When the plants are 2 or 3 in. high a few twigs may be placed among them, to which they will cling. The flowers are produced in July, and the more liberally they are gathered the longer the plants will continue to bloom. Height, 3 ft.

Pelargonium.–The shrubby kinds will grow well in any rich soil; loam and decayed leaves form a good compost for them. They require good drainage and plenty of air and light while in a vigorous state. Cuttings root readily in either soil or sand, especially if placed under glass. Most of the hard-wooded varieties are more easily increased by cuttings from the roots. The tuberous-rooted ones should be kept quite dry while dormant, and may be increased by small off-sets from the roots.

Pentstemon.–This charming hardy perennial is deserving of a place in every garden. It may be grown in any good soil, but a mixture of loam and peat is most suitable. The seed may be sown in April, and the plants transferred when strong enough to their flowering quarters; or it may be sown in a sheltered position during August or September to stand the winter. It may also be increased by dividing the roots in spring, as soon as growth begins. Cuttings of the young side-shoots about 6 in. long may be taken at any period–the middle of September is a good time; these should be placed under a hand-glass in sandy loam and leaf-mould. These cuttings will flower the first year. It blooms from May to October. Height, 2 ft.

Peppermint.–This may be grown on any damp or marshy soil, and increased by dividing the roots.

Perennials.–These are plants that die down during the winter, but spring up and produce new stems annually. Some, as for instance Antirrhinums and Pansies, flower the first season, but usually they do not bloom till the second season. Many of the species improve by age, forming large clumps or bushes. The stock is increased by division of the roots, which, if judiciously done, improves the plant. Like annuals, they are divided into classes of Hardy, Half-hardy, and Tender plants.

Hardy perennials do not require artificial heat to germinate the seeds, or at any period of their growth, but are the most easily cultivated of all plants. Seed may be sown from March to midsummer, transplanting in the autumn to their flowering quarters; or it may be sown in August and September in a sheltered position to stand the winter.

Half-hardy plants require artificial heat to germinate their seed, and must be gradually introduced into the open. They may be sown during March and April in frames or a greenhouse, when many will bloom the first season. If sown between May and the end of August they will flower the following spring and summer. They require protection during winter, such as is afforded by a cold pit, frame, or greenhouse, or the covering of a mat or litter. Tender perennials may be sown as directed above, but the plants should be kept constantly under glass.

Some perennials, such as Pinks, Carnations, Saxifrages, etc., do not die down, but retain their leaves. These are called evergreen perennials.

Pergularia.–Very fragrant twining plants, suitable for trellis-work, arbours, etc. A rich soil suits them best. They are easily increased by cuttings sown in sand under glass. They flower at midsummer. Height, 8 ft. to 12 ft.

Perilla Nankinensis.–A plant of little merit, except for its foliage, which is of a rich bronze purple. It bears a cream-coloured flower in July. It may be raised in the same manner as other half-hardy annuals, and prefers a light, loamy soil. Height, 1 1/2 ft.

Periploca Graeca.–A hardy, deciduous, twining shrub, which will grow in any soil, and may be increased by layers or by cuttings placed under glass. It flowers in July. Height, 10 ft.

Periwinkle.–_See_ “Vinca.”

Pernettya.–An American evergreen shrub, which, like all of its class, thrives best in sandy peat; it delights in partial shade, and a moist
