omed in pots may be planted in the north border of
the garden in July, where they may shed their seed, from which early
plants will be produced. They may also be increased by off-sets. If
the old plants are cut down and kept well watered they will throw
up suckers, which may be separated and potted off into thumb pots,
transplanting into larger ones when required. They must _always_ be
kept shaded from the sun. A cool frame suits them in summer, and being
nearly hardy, should never be subjected to a forcing temperature,
sufficient heat to keep away frost and damp being all that is
necessary.

Cinnamon Plant.--This is a stove or greenhouse plant, and requires a
loam and peat soil. Cuttings of the ripe wood strike freely.

Cissus Orientalis.--Useful climbing plants which delight in a light,
rich soil. They are increased by cuttings planted under glass and kept
in a gentle, moist heat.

Cistus (_Rock Rose_).--A compost of loam and peat suits these
beautiful evergreen shrubs. They may be increased by layers, ripe
cuttings covered with a hand-glass, or seed. Though the plants are
pretty hardy it is advisable to afford them protection during severe
frosts. June is their flowering month. Height, 3 ft. to 6 ft.

Citrus Japonica.--A greenhouse evergreen tree, requiring a rich loamy
soil. Very little water should be given it while in a growing state.
It is generally budded on an orange or lemon tree and plunged in a
bottom-heat. June is its flowering season. Height, 5 ft.

Cladanthus.--The annuals may be sown in the open in April to flower in
July. The greenhouse evergreens may be propagated by cuttings under
glass. These produce flowers in June.

Clarkia.--These hardy annuals make a pretty display in the borders
during summer. Seed ripens plentifully, and merely requires sowing in
the open in March, or in September if protected in winter. The bloom
lasts from June to September. Height, 18 in.

Claytonia Sibirica.--A hardy herbaceous plant which yields light
yellow flowers in June. It is not particular as to soil, and may be
raised from seed sown either in autumn or spring. It stands division
of the root. Height, 4 ft.

Clematis (_Virgin's Bower_).--These plants like a dry situation. They
will grow in smoky districts, and may be increased by cuttings of firm
side-shoots under a glass in summer or by layers in September. With
the protection of a greenhouse they come into flower early in spring.
They are the most beautifu
