Colutea, an ancient name of a bush with sweet-scented flowers. The genus includes a number of species of shrubs, with yellow or orange, pea-shaped flowers, which are succeeded by seed-vessels like bladders.

C. arborescens grows about ten feet high, with yellow flowers, in June and July. C. cruenta, four feet high, with reddish flowers; and C. Pocockii, with dark-yellow flowers. All are free growers, and well adapted to introduce into extensive shrubberies.
