l of all flowering hardy climbers. The stove
and greenhouse varieties are best planted in loam and peat, though
they will thrive in any light soil. Any good garden soil suits the
hardy kinds. The herbaceous varieties are increased by dividing the
roots early in spring. They bloom at various periods. After they have
ceased to flower, the Jackmanni and Viticella sections should be cut
down to within 9 or 12 in. of the ground. The Patens and Florida
do not require pruning; those of the Lanuginosa should be cut back
moderately, but not too close. A good dressing of leaf-mould and
manure should be dug in about November. Heights vary from 2 ft. to 20
ft. (_See also_ "Traveller's Joy.")

Cleome.--The species of this genus are very pretty and free flowering,
some being half-hardy climbers notable for their foliage. They like
a rich, light soil. Cuttings of the stove kinds root freely under a
glass. Some of the annual species require to be sown in a hotbed frame
or in a hot-house, then potted off and placed with tender annuals. The
hardier ones may be sown on a hotbed, and afterwards planted out in a
sheltered position. They flower in May, June, and July. Heights vary
from 6 in. to 8 ft.

Clethra Alnifolia.--This hardy deciduous shrub bears in September
deliciously scented pure white flowers on the side-shoots of the
previous year's growth. It needs a light soil and a dry, sunny
situation. It may be propagated by cuttings placed under glass in
sandy loam, or by suckers taken when the leaves have fallen, but is
more generally increased by layers. Height, 3 ft.

Clianthus.--A genus of very elegant, free-flowering, evergreen
greenhouse shrubs. They flourish in the border of the conservatory (or
against a south wall if protected from cold) in an equal mixture of
loam, peat, and sand. Cuttings root freely in the same soil under
glass. Seed sown early in spring produce flowers the first year, in
May. Height, 3 ft. to 4 ft.

Clintonia.--Very pretty half-hardy annuals; useful for beds, edging,
pots, or rock-work. They produce an abundance of Lobelia-like flowers
in August. Sow the seed in the open in spring. Height, 6 in.

Clitoria.--A greenhouse climbing or trailing plant, which thrives in a
mixture of loam, peat, and sand. Cuttings will strike in heat, but it
is more readily grown from seed.

Clivias (_Caffre Lilies_).--Most beautiful evergreen plants for
the greenhouse. The soil most suitable for them is a compost of
leaf-mou
