Penstemon rupicola is a species of penstemon known by the common names cliff beardtongue or rock penstemon.[1] It is native to the west coast of the United States from Washington to the Klamath Mountains of far northern California, where it grows in rocky mountainous habitat. It is a clumpy, mat-forming subshrub growing no more than 14 centimeters high. The thick, waxy, oppositely arranged leaves are round or oval and up to 2 centimeters long. The showy wide-mouthed tubular flowers emerging from the mat may be nearly 4 centimeters in length and are shades of light purple to bright pink.
Penstemon rupicola is included in Penstemon subgenus Dasanthera, along with P. barrettiae, , P. davidsonii, , P. fruticosus, , , and P. newberryi.[2]
