Penstemon Holly's White
Penstemon Holly's White puts on a great show of white flowers through the Spring, Summer and Fall. Penstemon Holly's White is at its best for two to three years. In order to continue to thrive new parts of Penstemon Holly's White must layer into the garden soil. Penstemon Holly's White is great for quickly filling in a young garden or a newly opened space. I regularly trim off the dead flower stalks to keep the plants blooming. I cut Penstemon Holly's White back heavily in the late winter. The Penstemon gloxinoides group will take temperatures down to 10° F. The upper parts of the plants will be damaged in the upper to mid teens. I have sometimes had trouble with mites and have cut off the affected portions to fairly good success even when this means nearly cutting Penstemon Holly's White to the ground. Penstemon Holly's White attracts the Variable Checkerspot and is a potential larval food source for the Common Buckeye Butterfly and could be a nice addition to your butterfly garden.
