Beautiful shrubby wildflower that shows up on rocky bluffs throughout the dry interior of B.C. Hardy at least to Zone 2; the common thing about every site where it thrives in the wild is the excellent drainage. I've added a few photos I took earlier this year, May 2010.

This has been another relatively long-lived penstemon for me. This species is a member of the dasyanthera section; most of which are evergreen sub-shrubs and natives of the Pacific Northwest. As a result, they are not as hardy as the great plains, Rockies or Great basin species. However, they are much more tolerant of wet climates than most penstemosn and actually do better in soils that are more acidic. For gardeners in eastern North America, the dasyanthera section are the best penstemons for us to grow. Other species in this group are P. cardwellii, P. rupicola, P. lyalii, P. scoulei and P. newberryii.
