Bambara groundnut (Vigna subterranea (L.) Verdc.) is indigenous to west central Africa. Most of its current production is in Africa, but the plant is also cultivated in India, Southeast Asia, Australia, and Central and South America. The plant has an interesting growth habit in that after pollination, the developing pod and seeds are pushed into the ground, where they grow until full maturity. Plants are typically uprooted at harvest to collect the seeds and pods; because of this subterranean growth, they have acquired the common name groundnut. Mature seeds are boiled and consumed as a cooked seed, prepared as porridge, or milled into a flour to form cakes. Immature seeds are also harvested and cooked as a fresh vegetable.
