Psophocarpus tetragonolobus, commonly known as the winged bean, is a vigorous tropical climbing legume of the Fabaceae family, renowned for its exceptional versatility and nutritional value. The plant produces trifoliate bright green leaves and striking pale purple to violet flowers that attract pollinators. Its most distinctive feature is the elongated pods with characteristic winged edges, which, along with its leaves, flowers, roots, and seeds, are all edible and highly nutritious. Winged bean thrives in warm tropical and subtropical climates, preferring well-draining fertile soils and full sun, and it requires support structures for optimal growth. Rich in protein, vitamins, and minerals, it is valued both as a human food source and as livestock fodder. Additionally, as a nitrogen-fixing legume, Psophocarpus tetragonolobus contributes to soil fertility, making it an important crop in sustainable agricultural systems.
