Penstemon Red Rocks
Penstemon Red Rocks puts on a great show of pinkish red flowers. Penstemon Red Rocks is a hybrid of Penstemon mexicali. Compared to the Penstemon gloxinoides group, I have had less pest issues with these hybrids. The plants tend to flop more but produce more flowers. Penstemon Red Rocks is drought tolerant but will flower best with a moderate amount of water. 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 Red Rocks back heavily in the late winter. If the plants air-layer on their own they can extend their lifespan significantly. 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.
