English names for the plant include tipsin, teepsenee, breadroot, breadroot scurf pea, pomme blanche, and prairie turnip.Several densely-haired stems emerge from the ground and reach up to 30 cm, bearing palmately compound leaves divided into five leaflets. Summer produces abundant blue or purple
flower s in terminal clusters 5 to 10 cm long, leading to flattened, slender-tipped pods.The plant grows from one or more sturdy brown roots which form rounded tuberous bodies about 7 to 10 cm below the surface, each 4 to 10 cm long. These can be eaten raw, dried, or cooked. The raw root is moderately sweet and tastes like the turnip. The dried root can be ground into a
