Rocky Mountain Penstemon is a semi-evergreen, native, perennial forb with fibrous roots. It is native to the western United States from southern Wyoming south into northern New Mexico, and the eastern portions of Utah and Arizona. It is found with sagebrush in pinyon-juniper woodland, oak scrub and in openings of ponderosa pine and spruce-aspen forests. It is best adapted to well drained, rocky and sandy loam soils that are weakly acidic to alkaline and in areas with 15-20 inches annual precipitation  and 6,000-10,500 feet elevation.

The beautiful flowers and evergreen basal leaves of Rocky Mountain penstemon make it attractive for ornamental and landscape planting. It is frequently used in seed mixes for erosion control and reclamation. Rocky Mountain Penstemon is a common ingredient in our wildflower mixes, erosion control and reclamation seed mixes.

Rocky Mountain penstemon is used by wildlife and is rated as fair forage for cattle and fair to good forage for sheep. It provides diversity in the plant communities where it is found. Rocky Mountain penstemon is used by bumblebees to gather nectar and is also visited by various other bees and wasps. Hummingbirds only visit Rocky Mountain penstemon occasionally.

To establish Rocky Mountain Penstemon the recommendation is to plant seed in the fall from 1/8 to no more than 1⁄4 inch depth into a firm, weed-free seedbed. Good seed to soil contact is important for germination and establishment. Mulching, irrigation and weed control benefit stand establishment. Some seed may not germinate until the second growing season. Plants begin growth early in the spring and flower blossoms appear in the late spring and early summer. Flowering should not be expected until the second growing season.
