Penstemon Dark Towers (PP 20,013) is a three-foot-tall hybrid beardtongue that blooms with light pink flowers in late spring/early summer. The flowers contrast nicely with the plant's beautiful wine-red foliage. Dark Towers Beardtongue is well adapted to moister growing conditions found in the eastern half of the US where many beardtongues of Western origins will fail. But with just a little extra water, this cultivar also thrives West of the Mississippi as well. The ornamental foliage generally retains good color throughout summer and the plant forms decorative seedheads, making it an excellent companion plant for many warm season ornamental grasses. 'Dark Towers' Penstemon is a hybrid of Penstemon digitalis 'Husker Red' and Penstemon 'Prairie Splendor' developed and introduced by Dale Lindgren at the University of Nebraska. Companion plants include ornamental grasses, Purple Coneflower (Echinacea) and Poppy Mallow (Callirhoe).
