Abstract

Royal penstemon is chiefly used as a forb component for wildlife habitat enhancement projects and restoration efforts. Its showy flowers attract numerous pollinators and other insects which provide a food source for birds and other vertebrates. This species is also commonly used in xeriscaping and other low-water-use landscaping. It is also suited for roadsides and other beautification projects.
