The compound leaves have three leaflets. The white, purple, or pale-yellow flowers usually grow in twos or threes at the ends of long stalks. The pods are long and cylindrical. In the southern U.S. the cowpea is grown extensively as a hay crop, as a cover or green-manure crop, or for the edible beans.
