Azuki Bean

The azuki bean (アズキ（小豆）, azuki?, also spelled 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.
