Chapter 11

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 _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.
