Eriogonum deserticola is found primarily in the moving sand dunes in the southern Salton Sea basin of extreme eastern San Diego and Imperial counties, California, with small populations in Yuma County, Arizona, and Baja California and Sonora, Mexico, where the species can be locally abundant. The larger plants are continually being buried and then uncovered by moving sand, revealing slender, grotesquely twisted trunks. R. S. Felger (2000) reported seeing some of the “exposed lateral roots” being up to six or more meters in length. It appears that the leaves are frequently stripped away by wind-blown sand.

Eriogonum viridescens is infrequent in the Inner Coast and the Transverse ranges (Fresno, Kern, Kings, Los Angeles, Merced, Monterey, Riverside, San Benito, western San Bernardino, San Luis Obispo, Santa Barbara, and Ventura counties). Unlike those of the more widespread E. maculatum, the outer tepals of E. viridescens are swollen apically, rather than basally. A collection made at Crystal Springs in the Coso Mountains of Inyo County (Coville & Funston 909, DS, US) probably is accurately labeled but the location remains to be confirmed by modern collections.
