Psophocarpus tetragonolobus, the winged bean is a strong growing, twining perennial legume to 1.8m with large beautiful pale blue flowers. The plant is thought to have originated along the east coast of Africa and is used for leafy green potherbs, fresh pods, dried beans, edible tubers, animal fodder and forage, green manure, and cover crops; the winged beans are the ultimate multi-purpose crop. Young seedpods cooked for a few minutes taste like French beans but the roots and foliage can also be used. Not frost hardy.
