Description

Penstemon digitalis is a clump-forming perennial in the plantain family that can be found in the mountains of NC. It grows up to 5 feet tall in prairies, wood margins and open woods of eastern and central USA. In late spring to early summer tall clusters of showy white tubular flowers appear that attract bees, hummingbirds, and butterflies. No serious disease or pest problems.

This plant adapts easily to cultivation and prefers well-drained, moist to dry loamy soils and tolerates clay soil if it is well-drained. Plant in full sun to light shade in small groups in the native/pollinator garden, naturalized areas or borders.
