Eriogonum ovalifolium is a highly diverse and widespread complex of generally distinct but sometimes intergrading varieties. Several varieties are in cultivation and make worthy additions, especially to the rock garden. The dimorphic nature of the tepals is obvious only in fully mature flowers. In some populations of the more depauperate varieties, such as var. nivale and var. depressum, the tepals may not be as distinctly dimorphic. Nonetheless, the overall aspect of the species is unmistakable.

There are several reports of traditional use of Eriogonum ovalifolium by Native Americans. P. Train et al. (1941) indicated that a decoction of the roots is used in Nevada for colds. R. V. Chamberlin (1911) reported that the Gosiute Indians in southwestern Utah used it in a poultice or wash to treat venereal diseases.

Members of the species are food plants for Bauer's dotted-blue butterfly (Euphilotes baueri).
