Neutral altagardener On Nov 9, 2008, altagardener from Calgary, AB (Zone 3b) wrote:

From Flora of Alberta (Moss and Packer):
"Stems mostly 1-3 dm high, forming loose mats from a procumbent woody base, the branches minutely puberulent; leaves broadly elliptical or rotund, entire or distantly toothed, the lower short-petioled; calyx densely viscid-puberulent, the lobes attentuate; corolla 3-3.5 cm long, light violet-purple, strongly widened at the throat; anthers woolly; sterile stamen short, bearded with yellowish hairs." Habitat: "Rocky banks and slopes at subalpine elevations." Range: "southeast BC, Alberta south to Idaho, Montana."

Grows naturally in limestone rubble in this area.

This is another beard tongue from the Dasanthera section. It is an evergreen sub-shrub and is very closely related to P. fruticosus. This species has relatively large flowers that are pinkish-lavender. ideal in the rock garden. It can tolerate wetter climates than most penstemon and prefers slightly acid soil. Has done well for me in Newfoundland.
