The large, fragrant flowers are white, reddish, or purple; they are in axillary racemes. The fruit is a pod, with three or four globose, ovate, or flattened seeds. The hyacinth bean has been cultivated since ancient times for food and forage; it does not grow wild. It is cultivated primarily in the tropical and subtropical regions of Asia and Africa.
