Water Saving Tip:

Change spray sprinklers to low-flow bubbler or drip systems. Shrubs and trees are ideal candidates for this type of irrigation because the water is applied directly to the root zones.

  • Description

  • Notes

Rocky Mountain penstemon is one of the most common native penstemon and for good reason. It is both cold and drought tolerant, and has stunning violet blue to blue flowers from June to August. It varies in size, from 1 to 3 feet, and tends to be narrow, even when taller. Basal leaves are bright green and evergreen. Attractive to bees and hummingbirds. Also is a nice cut flower. A Utah native.
Grow in full sun and well drained soils. Will tolerate alkaline soils to 8 pH. Gravelly, sandy-loam, and clay-loam soils.
