Penstemon ‘Dark Towers’

Tall Beard-tongue

USDA Zone: 3-9

Plant number: 1.405.670

Developed at the University of Nebraska, this is an outstanding taller selection for the middle to back of a sunny border. It forms a mound of deep purple-red foliage, bearing spikes of bicolor soft and deep-pink bell-shaped flowers in summer. An easy border plant, also tolerant of heat and humidity. Terrific as a cut flower. In particularly rich soil this may need to be staked. A 2008 introduction from TerraNova Nurseries in Oregon. USPP#20013: unlicensed propagation prohibited. Registered with COPF.
