Noteworthy Characteristics

Penstemon digitalis is a clump-forming, Missouri-native perennial which typically grows 3-5′ tall and occurs in prairies, fields, wood margins, open woods and along railroad tracks. Features white, two-lipped, tubular flowers (to 1.25″ long) borne in panicles atop erect, rigid stems. Flowers bloom mid-spring to early summer. Basal leaves are elliptic and stem leaves are lance-shaped to oblong.

Genus name comes from the Greek words penta meaning five and stemon meaning stamen in reference to each flower having five stamens (four are fertile and one is sterile).

Specific epithet comes from the Latin digitus meaning finger for flowers that look like the finger of a glove.

Penstemon is sometimes commonly called beard tongue because the sterile stamen has a tuft of small hairs.
