Practical Information

Uses
Breadroot scurf-pea probably was the most important wild food gathered by Native Americans of the Great Plains. The tuberous root can be eaten raw, cooked, or dried. By mid-summer, the leaves and stem break off and blow away. Plains tribes dug the tubers before the tops were gone and often dried them for winter use.

Additional Notes

Comments

Breadroot scurf-pea will decrease with grazing and is uncommon outside of undisturbed prairie.
