Also called scurfy pea or manyflower scurfpea. This native legume resembles domesticated alfalfa, but has smaller and narrower leaves that grow less thickly. During late summer, the stem breaks off and the plant blows like a tumbleweed across the prairie, scattering its seeds.
Wild alfalfa is fairly drought resistant, with roots going down ten feet.
Livestock do not particularly like it, but will consume it during its early growth stages, or when it has been cured in prairie hay.
