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.) |
Varieties 2 (2 in the flora). Eriogonum hoffmannii is known only from the Death Valley region (M. DeDecker 1974) of Inyo County. Nearly all of its known populations are within the boundaries of Death Valley National Park (a few plants occur just to the west along California Highway 190 southeast of Travertine Point). It is of special concern but is well managed and protected. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
