Penstemon angustifolius var. vernalensis var. vernalensis
Vernal narrow-leaf penstemon is a scarce variety native to the Colorado Plateau region, thriving in well-drained sandy or gravelly soils in full sun to light shade. It is exceptionally low-maintenance once established and requires minimal irrigation beyond natural rainfall. This uncommon penstemon is highly rewarding for pollinator gardens and native plant landscapes in the Intermountain West.
