Prairie Beardtongue produces large, lavender to purple tubular flowers with white throats striped with purple lines that serve as nectar guides for pollinators. Native to dry limestone prairies and glades across the south-central United States, it grows 1–2 feet tall. This is one of the showiest penstemons in its region, often cultivated in rock gardens and native plantings. It is adapted to thin, rocky, alkaline soils where few other wildflowers thrive.
