A genus of about forty species of shrubs bearing pea-shaped flowers in great abundance. They are of very easy culture, and, without irrigation, grow freely in any soil, even the poorest.

Propagate by seeds sown one-quarter of an inch deep in the open ground or in a cold frame in early Spring. When the seedlings are four inches high, transplant them into nursery rows and grow them on until required. Cytisus racemosus and others of the class may also be increased by cuttings, placed in a cold frame in October, and shaded from sunshine until rooted, when they should be potted singly in small pots.
