Adzuki bean

Patent Granted The azuki bean (from the Japanese アズキ（小豆） (azuki?)), also known as adzuki or aduki, is an annual vine, Vigna angularis, widely grown throughout East Asia and the Himalayas for its small (approximately 5 mm) bean. The cultivars most familiar in Northeast Asia have a uniform red color. However, white, black, gray and variously mottled varieties are also known. Scientists presume Vigna angularis var. nipponensis is the progenitor.
