Hope you are a member of The Sedum Society then. The Cuttings Exchange is a great way to increase the number of plants in your collection.
Very nice collection and I love the red ones. They just seem to catch your eye when you look at them with the lighter stones. I used to have the barrel planters, I think mine lasted over 30 years and we brought them with us every home we moved to....when we took them apart to dispose of them, we had a family of mice under them, we had put a false bottom in them so I didn't have to use so much dirt in them and it provided nice protection for them.
