Penstemon Firebird puts on a great show of red flowers. 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 Firebird back heavily in the late winter. If the plants air-layer on their own they can extend their lifespan significantly. 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.
