Penstemon isophyllus, the equal-leaved penstemon, is a species of flowering plant in the plantain family Plantaginaceae, native to Mexico.

It is a recipient of the Royal Horticultural Society's Award of Garden Merit.[1]

Growing to 70 cm (28 in), it is a woody evergreen perennial with reddish pink tubular flowers. Although hardy to −10 °C (14 °F), it benefits from some winter protection in colder areas.

The Latin specific epithet isophyllus means "with leaves all of the same size".[2]
