Penstemon digitalis, otherwise known as foxglove beardtongue, is an upright, clump-forming perennial found in prairies, wood margins, and open forests through the eastern half of the United States. Growing to between two and five feet tall, Penstemon digitalis is perhaps best known for its tall spikes of white to pink colored foxglove-like flowers, which make up most of the plants' height and attract bees, butterflies, and hummingbirds.
Penstemon digitalis thrives in full to part sun in any well-draining, medium moisture soil, though it tolerates a wide variety of soil conditions and even dry shade. In addition to its versatility in the garden, foxglove beardtongue has the added advantage of semi-evergreen foliage; though the plants' tall flower spikes are relatively short-lived, the plants' basal foliage is very long lasting, and turns from bright green to a dark, burgundy wine color in cooler weather, adding multi-season appeal.
