Penstemon, the beardtongues, is a large genus of North American and East Asian flowering plants formerly placed in the Scrophulariaceae family (Cronquist system). Due to new genetic research, it has now been placed in the vastly expanded family Plantaginaceae.
These plants have opposite leaves, partly tube-shaped, and two-lipped flowers and seed capsules. The most distinctive feature of the genus is the prominent staminode, an infertile stamen. The staminode takes a variety of forms in the different species; while typically a long straight filament extending to the mouth of the corolla, some are longer and extremely hairy, giving the general appearance of an open mouth with a fuzzy tongue protruding and inspiring the common name beardtongue.
