About

This is a perennial herb forming a clump of short, erect stems. The leaves are made up of several pairs of leaflets 1 to 3 centimeters (0.4 to 1.2 in) long each. The inflorescence is a dense raceme of two to five white or pink pea flowers, each roughly 2 cm (0.8 in) long. The fruit is a hairless legume pod.
