Heuchera sanguinea
Heuchera novamexicana
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 novamexicana occurs in the mountains of Arizona and New Mexico. Populations with glabrous petioles may be found in the Organ Mountains of New Mexico; elsewhere, long stipitate-glandular petioles are more common in the species.
The Navajo Indians took a decoction of roots of Heuchera novamexicana for internal pain. They applied a poultice of split roots to infected sores, swellings, and fractures, and used the plant as a panacea or “life medicine” (D. E. Moerman 1998).
