Discussion

Heuchera sanguinea occurs in the southwestern United States and northern Chihuahua, Mexico, and is widely cultivated throughout the cooler parts of North America.

Heuchera sanguinea varies considerably within populations in shape, lobing, and size of leaves, in amount of hairs, and in shape, form, and color of flowers. Rydberg recognized var. pulchra as characterized by denser inflorescences and longer hairs on its pedicels, inferior part of the ovary, and sepals. Mixed populations with individuals bearing longer and shorter hairs can be found throughout the range of the species, especially in Arizona. It seems best to recognize H. sanguinea as a variable species without infraspecific taxa.

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.
