USDA Native Status: L48 (N)
A strong, woody taproot supports the more-or-less prostrate, branched stems which form a mat-like clump up to 1 ft. wide. Leaves, on long, slender stalks, are oval to heart-shaped. Matted clumps of basal leaves with leafless stems and roundish clusters of tiny, whitish to deep yellow flowers. They are green above, white-woolly below. Creamy-white to deep yellow, tubular flowers are borne in rounded clusters on leafless stalks about 1 ft. tall.
This is a highly variable species in a genus of many species, most of which are difficult to distinguish from one another. The seeds are an important food for small wildlife, including ants. Eriogonum, from the Greek erion (wool) and gony (knee or joint), refers to the hairy stems of many species.
