This Clematis X Cartmanii "Joe" was on display at the Phila Flower Show, took 1st place BTW. I haven't had a chance to look this up yet. Does anyone have some info on this mini clematis. Is it a mini or is it just the way this one was grown. There is also a smaller one similar but not sure if the same one, that is sitting in front. It was growing on a small round trellis probably not more than a10 to 12 inch ring .
