Thanks for the list. I have some cristata. I keep forgetting that Columbine can be used in shade!
Do you have good luck with Trillum? I love them. I grew up in Michigan where it is against the law to pick or disturb the wild ones. They may like sandier soil than what I have though.
I will have to see if any of these are carried locally. Plant Delight's probably has many of them and they are just over in Raleigh.
