Penstemon ‘Dark Towers’ an improvement over another great garden plant, Penstemon ‘Husker Red’. P. ‘Dark Towers’ is the product of the breeding work of Dale Lindgren of the University of Nebraska. It is a dramatic specimen in the perennial border with beautiful narrow dark burgundy foliage that provides both eye catching colour and contrast in the garden throughout the season. The best colouring is achieved when the plant is grown in full sun. Burgundy flowering stems growing to 3 ft (36”) in height yield an abundance of soft pink tubular flowers that are much loved by both butterflies and hummingbirds. This perennial, hardy to zone three, will bloom from late spring into summer. Deadheading will encourage additional flowering. Heat and humidity tolerant
