I bought one of the Cathedral Rose Penstemons and it is so beautiful. I was wondering if any of you could provide any comments about its over-wintering ability. It says perennial on the tag, but I've noticed that they sometimes stretch the truth!

I was looking for a plant with blooms similar to Foxglove which would return each year. I think the blooms on this are perfect!

I am also impressed that you can just root cuttings of this in water!
