Penstemon digitalis is one of the few penstemons that thrives in clay. The white flowers bloom for a month or longer, and look great with the blue flowers of Ohio Spiderwort and Blue Eyed Grass. Only three feet high, this clump-forming perennial does well in full sun to light shade, and tolerates seasonally damp conditions. The tubular flowers attract long-tongued bees such as bumblebees and mason bees, as well as hummingbirds. Other common names include Foxglove Beardtongue and Mississippi Beardtongue.

Smooth Penstemon is a host plant for the Confused Haploa moth (Haploa confusa).
