This perennial herb grows up to 80 centimeters tall.[3] It has waxy, serrated leaves and blooms in tubular pink flowers between April and August.[2]
This plant grows only on volcanic fields around Sunset Crater in one Arizona county. It grows in openings and around Ponderosa pines.[3] It is a fire-adapted species.[4] It may be threatened by off-road vehicle use and by hybridization with other Penstemon.[5]
Aven Nelson first described the plant in 1927 as a subspecies of Penstemon pseudospectabilis M.E.Jones. In 1937 David D. Keck gave the plant a distinct species name based upon its narrow ecological niche.[6]
