Penstemon 'Catherine de la Mare', Beard Tongue

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!⁠ We cut this back after its heavy summer bloom and were excited to see continuous blooms through a few light frosts into November (and it's still not done!). We have included a photo of blooms in November which are more pink in the cold.  A P. heterophyllus cross found in the garden of Richard de la Mare in the 1950s and named for his wife.  Maximum size: 18 inches tall and wide⁠ Minimum temperature: 0° F
