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. At 3′ high this clump-forming perennial does well in full sun to light shade, and tolerates seasonally damp conditions.

Mass in sunny borders, wild gardens, native plant gardens or naturalized areas.
