Penstemon Raven

Penstemon Raven puts on a great show of flowers in the Spring and then repeats with fewer flowers in Summer and Fall. The flowers of Penstemon Raven are a dark dusky purple with a pale throat. Penstemon Raven will fade after two to three years but they do a tremendous job of quickly filling in a young garden or a newly opened space. I trim off the dead flowers and cut Penstemon Raven back heavily in the late winter and then less severely after each blooming cycle. If Penstemon Raven can air-layer on their own they extend their lifespan significantly. You can help this process by mulching heavily around the plants. The Penstemon gloxinoides group will take temperatures down to 10° F. I have sometimes had trouble with mites and have cut off the affected portions to fairly good success.Penstemon Margarita BOP is a potential larval food source for the Common Buckeye Butterfly and the Variable Checkerspot and could be a nice addition to your butterfly garden.
