Penstemon parryi is known from the scattered desert mountain ranges of southern Arizona in Cochise, Pima, Pinal, Santa Cruz, and Yavapai counties. The species resembles P. superbus; it is distinguished by its narrow leaves and corollas that are rose pink or rose magenta, more bilaterally symmetric, and white-pilose abaxially in the throats.
