This plant grows on clay soils in dry, open habitat. In Washington it grows in plant communities dominated by antelope bitterbrush (Purshia tridentata) and Indian ricegrass (Oryzopsis hymenoides), purple sage (Salvia dorrii) and bluebunch wheatgrass (Pseudoroegneria spicata), and rabbitbrush (Ericameria nauseosa).Penstemon eriantherus var. whitedii (Whited's penstemon). Washington Department of Natural Resources, Washington Natural Heritage Program and Bureau of Land Management. 2005. It occurs on rocky soils in sagebrush habitat. Its ability to live in a relatively rough habitat may help it persist in disturbed areas, such as eroded trails.Meinke, R. J.
