Beardtongue ‘Dark Towers’
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.
Penstemon 'Dark Towers'
Best planted in average or dry, well-drained soil.
Deep, purple-red leaves.
Tubular, lavender-pink flowers mid-spring to early summer.
