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 wootonii occurs in the Sacramento and White mountains of south-central New Mexico. It resembles H. parvifolia.
