RhÓdánthí:, Lindley. From rhodon, a rose, and anthos,

T h i s is one of the most delightful annuals ever
introduced to our collections. To obtain flowering
plants in March, the seed should^ be sown in
August, in a compost of decayed leaf-soil and light
maiden earth, in equal parts, having the pots well
drained. The seed-pots should not be placed in a
lower temperature than 60 nor ever higher than
80 degrees. The earth should never be allowed
to become too dry, taking care to apply water of a
t e m p e r a t u r e nearly equal to that of the house.
T h e y will require several shifts p r evious to flowering
; at the two last, viz. those in January and
March, decayed manure should be substituted for
leaf-mould, and a small portion of white sand
added to the compost; a second sowing should be
made in October and treated as the flrst, and they
will flower beautifully the fol lowing May ; and if a
final sowing is effected in March, the plants will
be ready to plant out in the flower-garden in May
or June, where they will flower during the autumnal
months. After the plants raised from any
of the sowings have been potted, they should be
removed to a much cooler house, and when pro-
[ 269 ]
perly established, placed on some elevated situation
near the glass. Seed should be obtained from the
plants grown in the greenhouse.

Rhododendron, Linn. From rhodon, a rose, and
dendron, a tree; because of the appearance of the
terminal bunches of flowers. Linn. 10, Or. 1, Nat .
Or. Ericacece. The Rhododendron is decidedly
one of the finest of all known genera, containing
some of the most handsome, elegant, and showy
s h r u b s ; all of which are admirably adapted cither
for ornamenting the greenhouse or shrubbery, or
for planting singly on lawns. Peat soil is most
suitable to these plants, but they may also be
grown in very sandy loam, or vegetable mould,
i'ropagation may be effected by layers or seeds; if
the latter mode be preferred, the seeds must be
sown early in spring, in flat pans filled with peat
soil, and the seed covered very slightly over ; tlie
pans should then be set in a close frame till the
plants make their appearance, taking care to wHter
very slightly when the soil appears dry. The
seedlings having attained to a sufficient height , so
as to admi t of their being drawn without fear of
i n j u r y , should be removed into other pots or pans,
using the same kind of mould. After this removal
they should be kept in a close f rame till fresh roots
are produced, and they may then, by decrees, be
hardened to the air. The small-wooded kinds may
be also increased very freely by young cuttings,
planted in sand under a glass. The tender kinds
may be easily propagated by young cuttings torn
off close to the stem, planted in sand and plunged
i n heat under a glass. Synonymes: 1. R. aromaticum..
