-A somewhat succulent genus of conservatory plants. They all
require a very rich loamy soil containing a little sand; and heat,
moisture, and shade are essential to their health. Cuttings 2 or 3 in.
long will root readily in spring or summer. Stand the cuttings in the
shade and do not over-water them; or they may be raised from seed sown
in March in a hot-house or frame having a temperature of 65 degrees.
Height, 1 ft. to 3 ft.

Tuberous Begonias should be planted in small pots placed in heat,
early in spring, and at intervals of a fortnight for succession, using
a compost of equal parts of fibrous loam, leaf-mould, and sand. Press
the soil rather firmly so as to promote sturdy growth, and only just
cover the top of the tuber. Water moderately till the plants begin to
grow freely. Gradually harden off, and plant out the last week in
May or early in June, or shift into larger pots for conservatory
decoration. Cuttings may be taken in April. The plants may also be
raised from seed sown in February or March in a temperature of 65
degrees. Before sowing mix the seed with silver sand, then sprinkle it
evenly over a box or pan of moist, fine, light loam and silver sand;
cover with a sheet of glass, and keep shaded. Transplant into small
pots, and pot on from time to time as the plants increase in size.
Plants so treated will flower in June or July. When the leaves of the
old plants turn yellow keep the roots quite dry, afterwards turn them
out of the pots and bury them in cocoa-nut fibre till January, when
they must be re-potted.

Belladonna Lily.--_See_ "Amaryllis."

Bellis Perennis.--_See_ "Daisies."

Benthamia.--An ornamental half-hardy shrub. A profuse bloomer, the
flowers of which are followed by edible strawberry-like fruit. Will
succeed in any good garden against a south wall. Easily raised from
seed or by layers. Flowers in August. Height, 3 ft.

Berberidopsis Corallina.--Distinct and very pretty evergreen climbing
shrubs, which prove hardy in the south and west, but need protection
in other places. They are not particular as to soil, and may be
increased by cuttings.

Bergamot _(Monardia Didyma_).--This hardy perennial will grow almost
anywhere, and may be increased by seed or by division of the root. It
flowers in _July_. Height, 4 ft.

Beta Cicla.--A hardy annual which succeeds in any common soil. Its
dark crimson and yellow flowers are borne in August. Height, 6 ft. It
is used as spinach. In Germany the m
