Eriogonum saxatile is found mainly in arid mountains of California (Fresno, Inyo, Kern, Los Angeles, Mono, Monterey, Riverside, San Benito, San Bernardino, Santa Barbara, Tulare, and Ventura counties) and Nevada (Esmeralda and western Nye counties). The plants vary considerably as to robustness, degree of branching, and sprawl of the caudex. The size and position of the leaves also vary, as does the density of tomentum on the blades. Flower color varies from white to rose or yellowish, but the deep yellow of E. crocatum is never seen in E. saxatile. The species is frequently cultivated and is an excellent plant for the rock garden. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum pendulum is a rare to locally uncommon shrub in the O’Brien-Waldo area of Josephine County, Oregon, and more common in the Siskiyou Mountains of Del Norte County, California, as far south as Gasquet. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
