Discussion
Varieties 3 (3 in the flora).
Penstemon barbatus is among the more widespread and conspicuous penstemons in the desert Southwest and Southern Rocky mountains. Putative hybrids reported between P. barbatus and P. comarrhenus, P. glaber, P. strictus, and P. virgatus were summarized by F. S. Crosswhite (1965); putative hybrids involving P. pseudoputus and P. putus also are suspected among some herbarium specimens. Penstemon barbatus is widely cultivated for its showy flowers; cultivars with yellow corollas also exist. Penstemon barbatus was reported for Suffolk County, Massachusetts (D. W. Magee and H. E. Ahles 2007); that report, or that those plants persisted outside of cultivation, has not been confirmed.
Various groups of Apache, Navajo, and Western Keres of Arizona and New Mexico used Penstemon barbatus for drugs, ceremonies, and decorations (D. E. Moerman 1998).
