Additional Info on Penstemons
Hi again Dawn
Just thought I would add, I think the variety you have listed is one of the hardier ones, however, always leave the older foliage on through the winter, this helps to protect the base of the plant from frosts. Once you start to see new growth appear at the base in the spring, this is the time to prune away the old foliage just above the new growth. If you can, take some cuttings during late summer as an insurance policy against the mother plant from dying during winter.
