Most of the stove and greenhouse species should be turned out of their
pots in autumn, and laid by in a dry place until spring, when they
should be re-potted and kept liberally supplied with water. A.
Reticulata and A. Striatifolia bloom best, however, when undisturbed.
Discontinue watering when the foliage shows signs of failing, but
avoid shrivelling the leaves. The hardy varieties should be planted
6 in. deep in light, well--drained soil, and allowed to remain
undisturbed for two or three years, when they will probably require
thinning out. They are increased by off-sets from the bulbs.
The Belladonna (Belladonna Lily) should be planted in June in a
sheltered border in rich, well-drained soil.
Formosissima (the Scarlet Jacobean Lily) is a gem for the
greenhouse, and very suitable for forcing, as it will bloom two or
three times in a season. It should be potted in February.
Lutea (Sternbergia) flowers in autumn. Plant 4 in. deep from October
to December.
Purpurea (Vallota Purpurea or Scarborough Lily) is a very beautiful
free bloomer. October and November or March and April are the most
favourable times for potting, but established plants should be
re-potted in June or July.
Ambrosia Mexicana.--A hardy annual of the simplest culture. Sow the
seed in spring in any fine garden soil. Height, 1-1/2 ft.
American Plants.--These thrive most in a peat or bog soil, but where
this cannot be obtained a good fertile loam, with a dressing of fresh
cow manure once in two years, may be used; or leaf-mould and soil from
the surface of pasture land, in the proportions of three parts of the
former to one of the latter. The soil should be chopped up and used
in a rough condition. Sickly plants with yellowish foliage may be
restored by applying liquid manure once a week during the month of
July. A light top-dressing of cow manure applied annually, and keeping
the roots free from stagnant water, will preserve the plants in good
health.
Ammobium.--Pretty hardy perennials which may be very easily raised
from seed on a sandy soil. Flower in June. Height, 2 ft.
Ampelopsis.--Handsome and rapid climbers, with noble foliage, some
changing to a deep crimson in autumn. The Veitchii clings to the wall
without nailing, and produces a profusion of lovely leaves which
change colour. Any of the varieties may be grown in common garden
soil, and may be increased by layers.
Anagallis (Pimpernel.)--Very pretty. Sow the hardy annuals in the
open early in March; the biennials or half-hardy perennials in pots in
a greenhouse or a frame, and plant out when strong enough. May also be
increased by cuttings planted in ordinary soil under glass. Flower in
July. Height, 6 in.
