Thanks Jennifer. Which method did you try with the clematis? I know layering should work I am just to impatient and don't think about it in the Fall. How many types are you growing?
My MIL always had columbine at her back door that returned every year or well maybe reseeded.
I have White Swan cones and they returned. I just want to add some others and I have heard that some are more hardy that others.
