Penstemon digitalis (foxglove beardtongue)

Penstemon digitalis

Penstemon digitalis is an upright, clump forming perennial wildflower featuring deep green leaves on strong upright stems. In summer, plants are topped by showy tubular snapdragon-like white flowers which are frequently visited by pollinators. It flourishes in sunny sites with wet or moist acid loamy soil but will perform well in most average garden conditions. Plants tolerate clay loam, sand, alkaline pH, heat, drought, part sun and dry shade. Deadheading to remove dried stalks in the fall will allow the lovely purplish rosettes to function as winter groundcover. Plants are pest and deer resistant.
