Vigna
Quick Summary
The genus Vigna comprises vines or erect herbs found in warm or tropical regions. These plants are part of the pea family and are characterized by trifoliolate leaves, yellowish or purplish flowers, and long, two-valved pods. A well-known member of this genus is the cowpea (Vigna unguiculata), native to West Africa. Cowpeas are cultivated for their edible legumes, which are a rich source of protein. They are also grown for hay and as green manure or cover crops. These plants are heat-adapted and drought-tolerant, with pods that can reach 20–30 cm in length. The genus was named after the Italian botanist Domenico Vigna.12
