This tremendous improvement over ‘Husker Red’ was developed by Penstemon expert Dale Lindgren of the University of Nebraska who also hybridized 'Husker Red'. In comparison, ‘Dark Towers’ PP20013 has much darker foliage that emerges wine purple and keeps its color much better through the summer heat. It grows a bit taller than ‘Husker Red’ and produces masses of pink, rather than white, flowers in early to midsummer depending on the zone.
Like all of our Penstemons, this one takes the heat and humidity in stride but is also very cold hardy. It continues to provide terrific color in the landscape all season long.
