The annuals (_Callistemma hortensis_), usually known as French, German,
or China Asters, are very extensively grown, both for beds and pots,
and their diversity and generally compact growth render them almost
universal favourites. They require a rich loamy soil, and as the roots
are produced near the surface, a mulching of rotten dung will be found
most beneficial. Seeds may be raised in a cold frame in March or April,
and, when the seedlings are large enough, they must be transplanted
into beds from 9in. to 12in. apart each way. If it is desired to have
them in pots, they may be removed thence with a good ball of earth
adhering just before they commence flowering, liberally watered, and
kept lightly shaded from the sun, until root action is resumed. Those
kinds required for exhibition purposes should have several of the side
shoots removed, so that the whole growing energy of the plant may be
centralised into from five to seven flower-heads, by which means fine
blooms may be obtained. The dwarf kinds are most valuable for bedding
and pots, as the taller kinds frequently require stakes for support.
The following are the most important sections:
=Betteridge's Prize.= Very beautifully formed and brilliantly
coloured varieties, unsurpassed for exhibition purposes. As this
class has rather a straggling habit of growth, it is less suitable
for bedding and borders than many of the others.
=Boltze's Miniature Bouquet Pyramidal.= Dwarf and elegant, in
compact bouquets of six or eight; the truss of flower-heads springs
directly from the ground, having only a few leaves at base. Colours
very varied. _h._ 6in. to 8in.
[Illustration: FIG. 183. TRUFFAUT'S PEONY-FLOWERED ASTER.]
[Illustration: FIG. 184. TRUFFAUT'S PERFECTION ASTER.]
=Crown.=* Distinct. The central portion, or disk, of the head of
flowers is pure white, surrounded by a broad margin of coloured ray
florets, such as purple, violet, crimson, rose, &c. Flower-heads
large, flat, freely produced. _h._ 1ft. to 1-1/2ft.
=Dwarf Chrysanthemum-flowered.=* In size of flower-heads and habit
of growth, this surpasses all other dwarf varieties. The flowers
are full, Chrysanthemum-shaped, produced in clusters, or bouquets,
from ten to twenty in a truss, very delicate and beautiful in
colour. _h._ 1ft.
=Dwarf Pyramidal= or =Dwarf Bouquet=. A pretty little class, and
extremely floriferous, each plant producing from twenty to fifty
heads of bloom. Some of the colours are: Exquisite carmine with
white points, white with blue or carmine points, white with salmon
centre, &c. _h._ 1ft.
=Improved Imbricate.= The best strain of pyramidal Asters with
recurved florets; fine regular form of flowers, double to the
centre, producing but few seeds. Colours very brilliant. _h._ 2ft.
=Improved Rose.= A handsome class, producing a branched head,
displaying no less than fifty large double flower-heads, the outer
florets finely imbricated, and filled up to the centre when quite
open. The colours are of great brilliancy, and of many shades. _h._
2ft.
=Pompone Goliath.=* Flower-heads globular, and florets very closely
set. Valuable for bouquets, as the flowers remain intact for a
considerable time.
=Pyramidal Hedgehog.= Singular and unique. Stems upright, and
branched; each branch terminated by a single flower-head, which is
filled up with quill-like florets. Colours various. _h._ 1-1/2ft.
=Truffaut's Pæony Perfection.=* Vigorous upright growers, having
large, hemispherical-formed heads of flowers with incurved florets,
4in. across. The colours also are very varied. _h._ about 2ft. See
Figs. 183 and 184.
[Illustration: FIG. 185. VICTORIA ASTER.]
=Victoria.=* One of the most popular classes of Asters grown;
flower-heads very double, imbricate, globular, 4in. in diameter,
from ten to twenty on a plant, of various shades. _h._ 1ft., with
a pyramidal habit. See Fig. 185.
=ASTERACANTHA= (from _aster_, a star, and _acantha_, a spine; referring
to the disposition of the spines). ORD. _Acanthaceæ_. A handsome
greenhouse herbaceous perennial, of easy culture in sandy loam. It
should be grown in a sunny position, and be kept moderately dry,
otherwise little but foliaceous growth will be produced; but, if thus
treated, it flowers freely. Propagated by divisions in spring; or by
seeds, sown in August.
=A. longifolia= (long-leaved). _fl._ yellow, in dense axillary
fascicles. July. _l._ lanceolate, tapering to the base, narrow,
sessile, serrately ciliated. Stem quadrangular. Plant rather hairy.
_h._ 2ft. India, 1781.
=ASTERACEÆ.= _See_ =Compositæ=.
=ASTEROCEPHALUS.= _See_ =Scabiosa=.
=ASTILBE= (from _a_, without, and _stilbe_, brilliancy; in allusion to
the inconspicuous flowers of some of the species). ORD. _Saxifragaceæ_.
Tall branching herbs, with triternate or biternate leaves, allied to
_Spiræa_, from which they differ in having not more than three carpels,
eight or ten stamens, and numerous albuminous seeds. They are all more
or less graceful, and some indispensable, either when grown in isolated
clumps, or intermingled with other herbaceous plants. They thrive well
in almost any rich garden soil, preferring damp positions, and are
easily propagated by division, which is best done in early spring.
_A. japonica_ is grown very extensively for decorative purposes, its
elegant spikes of pure white flowers rendering it especially valuable.
The majority of the plants cultivated are imported, but they may be
grown fairly well in this country in heavily manured soil. They should
be potted as early as possible in the autumn, and plunged in ashes
or fibre outside, when they will soon commence to root, after which
they may be placed in heat, and forced as required, always giving an
abundance of water. Indeed, the pots may be stood in pans of water,
especially when the plants are well furnished with growth.
=A. barbata= (bearded). A synonym of _A. japonica_.
=A. decandra= (ten-stamened). _fl._ white, in spicate racemose
panicles. May. _l._ biternate; leaflets cordate, deeply lobed and
serrated, glandular beneath, and on the petioles. _h._ 2ft. to 3ft.
North America, 1812.
[Illustration: FIG. 186. ASTILBE JAPONICA.]
=A. japonica= (Japanese).* _fl._ small, pure white, in large
branching racemose panicles. May. _l._ triternate or pinnate,
serrated. _h._ 1ft. to 2ft. Japan. This is best grown in pots, as
early frosts generally cut it down in the open air. SYNS. _Spiræa
barbata_ and _japonica_, also _Hoteia_ and _A. barbata_. See Fig
186.
=A. j. variegata= (variegated).* _l._ prettily variegated with
yellow; panicles much more dense than the type; indeed, it is far
superior in that respect.
[Illustration: FIG. 187. ASTILBE RIVULARIS.]
=A. rivularis= (brook).* _fl._ yellowish-white, or reddish, in
large panicled spikes. Late summer. _l._ biternate; leaflets ovate,
doubly serrated, villous beneath and on the petioles. _h._ 3ft.
Nepaul. A grand plant for the margins of lakes or damp woodlands.
See Fig. 187.
=A. rubra= (red).* _fl._ rose, very numerous, in dense panicles.
Late summer and autumn. _l._ biternate; leaflets oblique, cordate,
1in. to 2in. long, with elongated, serrated points. _h._ 4ft. to
6ft. India, 1851. A very pretty, but rare species; excellent for
sub-tropical gardening.
=A. Thunbergi= (Thunberg's).* _fl._ small, white, very numerous, in
erect, much branched, pyramidal panicles, with reddish and slightly
downy stalks. May. _l._ unequally pinnate or bipinnate; leaflets
broad, yellowish green, sharply toothed. _h._ 1-1/2ft. Japan, 1878.
This pretty little sub-shrub is extensively propagated on the
Continent for forcing purposes.
=ASTRAGALUS= (a name applied to a shrub by Greek writers). Milk Vetch.
ORD. _Leguminosæ_. A very large genus of hardy herbs or sub-shrubs.
Flowers in axillary clusters; standard larger than the wings. Leaves
unequally pinnate. About one hundred species have from time to
time been introduced in English gardens; many of these are lost to
cultivation; the comparative few here described are still generally
grown, and are good representative species. They are all of easy
culture. The shrubby kinds grow well in any light dry soil, and are
slowly increased by cuttings placed in a cold frame, or by seeds. The
herbaceous perennials prefer a dry light soil, and may be increased by
divisions or seeds; the latter mode is preferable, as many species are
very liable to die if transplanted or divided, which is at best but a
slow method. Seed should be sown in pots of sandy soil placed in a cold
frame as soon as ripe, or very early in the spring, as they may lie a
long time before germinating. The dwarfer species constitute admirable
rockwork plants, and can be grown in pots containing a mixture of loam,
peat, and sand. Seeds of the two annual species, _A. Cicer_ and _A.
Glaux_, merely require to be sown in the open border early in spring.
