'Husker Red' is one of the few penstemons that does well in wet winters and hot, humid summers. Ruby-toned leaves appear in spring, followed in late spring and early summer by 3-foot-high stems adorned by panicles of white blooms.  The flowers attract bees, hummingbirds, and butterflies, but the plants are not magnets for deer or rabbits. In autumn and winter, songbirds feast on the seed. For a stunning display, plant 'Husker Red' in groups. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120
