Well-grown specimens are very pretty when in flower in late
March.

CHIONANTHUS.--There are two species of Chionanthus, viz. the North
American Fringe tree (_C. virginica_) and its Japanese representative
_C. retusus_. They resemble each other very much, but the American form
is the better of the two. The Fringe trees are very charming when in
pots. Prune back hard after flowering and fully expose to the sun to
ensure plenty of flower buds. A moist soil is essential.

MEXICAN ORANGE FLOWER (_Choisya ternata_). This will bear its white
fragrant flower clusters in March in a greenhouse, and a succession is
maintained for some time. It is most satisfactory when grown altogether
in pots and plunged outside during the summer.

CLEMATISES.--Of late years the various forms of Clematis have been grown
largely under glass and used for various purposes, not only in the shape
of large specimens, but in pots five inches in diameter, the plant being
secured to a single stake and carrying several big showy flowers. Two
somewhat new continental varieties, Marcel Moser and Nelly Moser, have
proved very useful for this treatment. The plants flowered in small pots
are those that are propagated in the preceding spring and plunged out of
doors during the summer. The Himalayan _C. montana_ that flowers
naturally so early in the season readily responds to a little heat, and
in the greenhouse in spring it is almost as welcome as the New Zealand
_C. indivisa_.

CLETHRA.--Although _C. alnifolia_ does not flower until the autumn it
may be had in bloom in spring. Of course, it will not be so early as
shrubs that are naturally in beauty in the spring, but in May its white,
fragrant flowers should be seen. It requires a cool, moist soil and
sunshine, while prune moderately immediately after flowering. Lifted in
the autumn soon after the leaves drop, it will succeed well.

CORYLOPSIS SPICATA.--This reminds one of a small Hazel bush, and in
early spring before the leaves appear, the drooping clusters of fragrant
yellow flowers appear in profusion; simple protection is all that is
needed to get flowers quite early in the year, when it is very pretty in
the greenhouse. It thrives well kept permanently in pots, or it may be
lifted and potted in the autumn. No pruning is necessary.

CYTISUS (Broom).--The various Brooms are much admired, whether in the
open ground or under glass, and for the latter purpose they must be
established in pots, for their
