	The caraganas are deciduous unarmed or spiny shrubs with yellow, rarely whitish or pinkish flowers axillary and solitary or fascicled, followed by linear pods. The cultivated species are quite hardy, except a few Himalayan species. They grow in almost any soil, but best in a sandy soil and sunny position, and are well adapted for shrubberies. C. arborescens is the only one which grows into a small tree, and is of upright habit, like C. frutex, which is about half as high and more graceful; most of the other species are low shrubs, of usually spreading habit.

'''''Caragana''''' is a genus of about 80 species of [[flowering plant]]s in the family [[Fabaceae]], native to [[Asia]] and eastern [[Europe]].

They are [[shrub]]s or small [[tree]]s growing 1-6 m (3-20 ft) tall. They have even-pinnate [[leaf|leaves]] with small leaflets, and solitary or clustered mostly yellow (rarely white or pink) flowers and bearing seeds in a linear pod.

''Caragana'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Dark Dagger]].
