Cisterns

Cisterns for the accumulation of rain-water should be formed in connection with the gutters of the various buildings in the gardens, for no water is equal to it for the artificial supply of moisture to plants.

Cistus

Thirty-nine species and varieties. Hardy evergreen shrubs. Layers or ripened cuttings. Common soil.

Citha Reylum

Nine species. Stove evergreen trees. Cuttings. Peat and loam.

Citron

Citrus.

Cladanthus

Two species. Hardy annual and half hardy evergreen shrub. Seeds. Common soil.

Clarkia

Three species and variety. Hardy annuals. Seeds. Common soil.

Clary

(Salvia sclarea.) Its leaves are sometimes used in soups and medicated wines. A very small number of plants are sufficient for a family. Sow early in April, or a month earlier in any light-soiled border. Thin the plants to two feet apart. The sowing must be annual. Seed may be saved by allowing some plants to run up the next spring; they ripen their seed in September.

Climbers

Climbers are plants which attach themselves to supporters by their natural appendages, as either by their tendrils or by their hooks.

Clinopodium

Three species. Hardy herbaceous perennials. Division or seeds. Common soil.

Clintonia

Two species. Annuals. C. elegans may be sown where it is to remain in the open borders, but C. pulchella requires its seedlings to be raised in a green-house or under a frame. - "If it is sown as soon as the seed is ripe, in two-thirds leaf mould, and one-third common soil, with a little sand, care being taken to make the soil firm enough to prevent the seed from being dislodged in watering; where it is intended to have beds of it in the flower garden, it may be planted out in the beginning of March: none of the frosts that happen after that time will injure it.

"If the seedlings were planted out. in the autumn, early enough to take root in the soil before the winter, there is no doubt they would prove as hardy as any of the Californian annuals, and, like them, succeed better in that way, than if sown or planted out in the spring." - Gard. Chron.
