Discussion

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).
