From July to October, trumpet-shaped blooms of deep blue-purple dazzle us all, gradually shifting to opalescent sky blues. This vibrant, vigorous penstemon is a must-have for any pollinator garden and adds a rare blue flare to fall. Give this plant a shearing and some occasional water to extend the blooming period. Appreciates good drainage and full sun. Beeloved by hummingbirds, bees, and butterflies!
