Penstemon strictus
"Rocky Mountain penstemon is a 1-3 ft., evergreen perennial with multiple spires of large, royal-blue to purple flowers rising above low mats of foliage. The paired leaves range from narrow and grass-like to broad and lance-shaped depending on the variety. The two lobes of the tubular flowers’ upper lips project forward over the lower lips’ three deeply cut lobes." Lady Bird Johnson Wildflower Center http://www.wildflower.org/plants/result....
"Rocky Mountain penstemon is found with sagebrush in pinyon-juniper woodland, oak scrub and in openings of ponderosa pine and spruce-aspen forests." USDA
