Of conservation concern. Eriogonum arborescens is local and occasionally rare on Santa Cruz, Santa Rosa, and Anacapa islands in Santa Cruz and Ventura counties. The species is cultivated, and populations have become naturalized on the mainland from San Mateo County south to San Diego, in large part because of planting along highways. Every effort should be made to remove these naturalized populations from the mainland. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Eriogonum bicolor is common from Castle Valley and the San Rafael Swells of Carbon and Emery counties, Utah, eastward to Grand Valley of Grand County, Utah, and Mesa County, Colorado. It occurs to the south in Garfield, San Juan, Sevier, and Wayne counties of Utah, especially in Canyonlands National Park and the Grand Staircase-Escalante National Monument. The species is worthy of cultivation, although being a slow-growing perennial of rather specialized soils it is a challenge. Seed germination in garden plots is reasonably successful; transplanting is difficult. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
