Chamaerhodos
(from chamai, on the ground, and rodon, a rose; dwarf rose). ORD. Rosaceae. Pretty hardy herbaceous perennials, allied to Potentilla, but difficult to preserve through the winter, owing to excessive damp. Flowers white or purple, erect, solitary or paniculate, small. Leaves alternate, three-parted; divisions again split up into linear segments. They should be grown under a well-drained ledge of the rockery, or in pots, in a mixture of sand, peat, and loam; and should be placed on a dry shelf, in a cold frame, in winter, at which time they must be but sparingly watered, if at all. Increased by seeds, which should be sown as soon as ripe, in pots, in a cold frame. C. erectus (erect). fl. white; petals about equal in length to the calyx. July to August. l. multifid; segments linear. Stem straight, beset with glandular hairs, panicled. h. 6in. Rocky Mountains, &c., 1824. C. grandiflora (large-flowered). fl. white; petals twice the length of the calyx. June. l. divided into numerous linear segments, pubescent. Stems numerous, erect, leafy. h. 6in. Dahuria, 1828.
