Planted several of the varieties mentioned in Todd's article last summer and this summer. We are trying them as ground cover at the base of various trees in order to avoiding mowing or weed whacking too close to trees. Mulched them in and the display has been neat and pleasant all summer. Some have needed more water than others although I have been assurred that as they mature they should be somewhat drought tolerant. Next spring I will try using some clippings in pots as fillers.
