Penstemon Midnight

Penstemon Midnight puts on a great show of dark purple flowers from mid Spring through Fall. The plants are at their best for 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 Midnight back heavily in the late winter. If the plants air-layer on their own they get a new lease on life. Penstemon Midnight will survive Winter temperatures down into the low teens. I have sometimes had trouble with mites and have cut off the affected portions to fairly good success. Penstemon Midnight blooms best in full Sun. 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.
