Columbines have long been admired for their unique flower form and easy nature. William Guiness boasts all the fantastic attributes of traditional columbines, plus it features a chic colour palette of dark purple to black with contrasting white accents. In full bloom from late spring to early summer, the floral display it exhibits is nothing short of showstopping. Perennializing plants are drought tolerant; blooms attract bees and butterflies. Great for borders, cutting gardens and containers.
