It is native to western North America from central Canada to California to Texas, where it grows in sandy habitat, such as alluvial plains[1] and sagebrush.[3]

It is a perennial herb with a branching, heavily glandular stem growing 30 to 60 centimeters tall. The leaves are palmately compound, each made up of usually three linear or lance-shaped leaflets borne on a short petiole. The inflorescence is a raceme of flowers emerging from a leaf axil. Each flower is under a centimeter long with a pealike corolla in shades of light purple-blue to white. The fruit is a hairy, glandular, spherical legume.[1]

The Zuni people eat the fresh flowers to treat stomachaches.[4]
