Discussion | Heuchera elegans occurs in the mountains of southern California, chiefly in the San Gabriel Range in Los Angeles and San Bernardino counties and vicinity. It resembles H. caespitosa. This group is in need of phylogenetic study. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Of conservation concern. Heuchera maxima is found on the northern Channel Islands (Anacapa, Santa Cruz, Santa Rosa), Santa Barbara County. Heuchera maxima is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
