roots are few, descend deeply, and
therefore transplanting is difficult. They will not bear hard forcing,
but in a greenhouse may be had in flower by the end of March, or soon
after. If kept altogether in pots, cut them hard back after flowering to
encourage vigorous shoots for another year. Numerous sorts may be grown
in pots, particularly the Spanish Broom (_C. albus_), the common Broom
(_C. scoparius_), with the hybrid Andreanus and the sulphur-coloured _C.
praecox_.
DEUTZIA.--The pretty _D. gracilis_ is well known as one of the best of
all shrubs for early forcing, and the whole family is of great interest
as pot plants and out of doors. Of these smaller Deutzias some beautiful
hybrids have been raised, particularly _D. Lemoinei_, _D. hybrida
venusta_, and _D. kalmaeflora_, all of which may be forced almost, if
not quite, as readily as _D. gracilis_. The old and exhausted shoots of
these Deutzias should, if the shrubs are kept in pots, be cut away to
allow young and vigorous ones to develop. Though they may be had in
flower early, they are much appreciated in the greenhouse, even as late
as the month of May. The larger growing _D. crenata_, with its numerous
varieties, _Candidissima flore-pleno_, _Wellsii_, and _Watererii_ will
not bear hard forcing, but can be had in flower with little trouble in
April and May. Good, well-ripened bushes may be lifted in the autumn,
and if potted and carefully attended to they will flower well the
following spring.
DIERVILLA (WEIGELA).--Many of the Bush Honeysuckles, as the Weigelas are
called, will flower well in a cool house, but they do not last
sufficiently long in bloom to make them of great value for this purpose.
The best is the dark-coloured _Eva Rathke_, which grows naturally into a
neat bush; the flowers are of claret colouring.
HEATHS.--_Erica carnea_ is very pretty in a cool house in mid-winter,
all that is needed being to lift the clumps from the open ground, pot,
and keep watered; while the large-growing Portuguese Heath, _E.
lusitanica_, which flowers naturally in February in the open ground,
when the weather is not too severe, well repays glass protection at that
season.
FORSYTHIA.--The Forsythias flower in the open ground by the month of
March, and indoors, of course, much earlier. The most effective is _F.
suspensa_, which is naturally a climber, or, at all events, of loose and
rambling growth. When needed for pots, tie the principal shoots to a
stout sta
