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.
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, 1˝ 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, 1˝ 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.
