Discussion
Penstemon confertus is widespread in the Central, Northern, and Canadian Rocky mountains in southern Alberta, southern British Columbia, southwestern Saskatchewan, northern Idaho, western Montana, northeastern Oregon, and eastern Washington. Isolated populations are known in northern British Columbia (Lackman Lake) and southern Alaska (Haines). E. Heitz (1927) reported a chromosome number of 2n = ca. 16 for P. confertus; the voucher for that count has not been verified. Counts from reports by J. Clausen et al. (1940), D. D. Keck (1945), and R. Spellenberg (1971) all are 2n = 32. Putative hybrids between P. confertus and P. globosus have been documented in Idaho County, Idaho (D. V. Clark 1971).
The Thompson and Okanagan-Colville tribes of southern British Columbia and northeastern Washington use Penstemon confertus for drugs, food, and dye (D. E. Moerman 1998).
