Noteworthy Characteristics

This penstemon cultivar is a clump-forming perennial which typically grows 2-3' tall. Features white (sometimes with a pink blush), two-lipped, tubular flowers borne in panicles atop erect, rigid stems. Flowers bloom mid-spring to early summer. Leaves are maroon (hence the cultivar name). Basal leaves are elliptic and stem leaves are lance-shaped to oblong. Penstemon in Greek means five stamens (four are fertile and one is sterile). Penstemon is sometimes commonly called beard tongue because the sterile stamen has a tuft of small hairs. Perennial Plant Association Plant of the Year (1996).

Problems

No serious insect or disease problems. Root rot can occur in wet, poorly-drained soils. Leaf spots are occasional problems. Flowering can be quite profuse and support is sometimes necessary.

Garden Uses
