Discussion
Glabrous-leaved plants are characteristic on the prairies of most of the central and northern Great Plains, and in the foothills of the Central, Northern, and Canadian Rocky mountains. Puberulent-leaved plants from the Driftless Area of Wisconsin have been named var. wisconsinensis. Puberulent-leaved plants also occur in Alberta and in North Dakota (specimens from Barnes, Benton, Eddy, Pierce, Ramsey, Wells, and Williams counties have been seen), sometimes with glabrous-leaved plants. Penstemon gracilis is introduced in Indiana (K. Yatskievych 2000).
The roots of Penstemon gracilis are used by the Lakota of the northern Great Plains for protection from snakebites (D. E. Moerman 1998).
