Thickleaf Penstemon, also known as Thickleaf Beardedtongue, produces clusters of bluish-violet or purplish-lavender flowers in the late spring to early summer. This wildflower is widespread in the Great Basin area and the Western United States, thriving in well-drained, dry, gravelly, and medium to coarse-textured soils. Notably cold and drought-tolerant, it has low water requirements, is resistant to fire, and exhibits slight tolerance to both saline and acidic conditions. Thickleaf Penstemon is typically found in adapted sites across low to mid-elevations.


This species serves multiple purposes, being utilized for wildlife habitats and rangeland due to its green leaves persisting throughout the growing season, providing forage value. Penstemons, including Thickleaf Penstemon, are deemed desirable forages for deer, antelope, and birds. Additionally, they may offer cover for select small bird species. Beyond its ecological contributions, Thickleaf Penstemon is employed in beautification projects.
