A genus of shrubs and herbaceous plants, two of the former being hardy in Britain and others half hardy. The distinctive features of the genus are the pinnate leaves, the umbellate arrangement of the pea-shaped flowers, the long-clawed petals, and the curious seed-pods. The last are slender, round, and separated into several one-seeded compartments defined by a constriction of the pod. The two hardy species are of easy cultivation liking a moderately rich, well-drained, loamy soil and a sunny position. They are propagated by cuttings, which may be struck either in a soft condition (when bottom heat should be given) or later, when the growths are more woody, under a bell-glass, in a cold frame.
