S. L. Welsh et al. (2003) alluded to hybrid combinations involving Eriogonum corymbosum and other species. Aside from the instances involving E. brevicaule, discussed below, none has been confirmed. Most of the putative hybrids are misidentified specimens of E. lonchophyllum or collections of var. corymbosum in which the leaf-margins are not decidedly crisped, a feature usually seen only in fully mature plants.
Eriogonum corymbosum was widely used by Native Americans. P. A. Vestal (1940) reported that the Hopi pressed boiled stalks into cakes that, when dried, were eaten with salt. J. W. Fewkes (1896) indicated that boiled leaves were mixed with cornmeal and water, and then baked into a kind of bread. S. A. Weber and P. D. Seaman (1985) indicated that A. F. Whiting was aware of a decoction of leaves (probably from var. glutinosum) being used for headaches. Variety glutinosum also was used primarily to treat tuberculosis, or at least as a cough medicine (D. E. Moerman 1986).
Some of the expressions of Eriogonum corymbosum are attracting the interest of gardeners, a few are coming into cultivation, and several selections are now being developed. The plants are slow growing but can be transplanted with some degree of success. Members of the varieties are food plants for Ellis's dotted-blue butterfly (Euphilotes ellisi).
