We're so excited to offer this gorgeous LONG-LASTING, LONG-BLOOMING shrubby Penstemon! Spectacular floral color somewhere between indigo & deep, rich claret - 'Blackbird' blooms all the way from Summer through first frost. Taller & more robust than most Penstemons at 3+' tall by 3' wide, the ethereal trumpet-shaped blooms (to 2" long) cluster in masses at the top of upright stems, gently framed by brilliant evergreen foliage. We recommend that you cut it back in Winter to encourage happy, tidy growth. Needs VERY well-draining soil, but having said that, a bit of clay or sand will be well-tolerated! Some mulch around the crown will help encourage rapid drainage. Plant it next to the silvery foliage of Erigonum giganteum 'St. Catherine's Lace' for a knock-out side-by-side pairing. Great choice for a large container, too!
