I was at the Va. Arboretum Fall Plant Sale lots of beautiful plants and plant related items and crafts. Very nice show. There was a landscaper there and this was their display. When I told her that I had friends that would just go crazy over their display she said take some pics so I did. This is a very doable project it was about 4ft wide 8ft long. You would need some kind of center fountain, copper pipe or tubing, section of gutter, ceramic tiles or slate, wood for the frame maybe some wire or metal grid for under the sedums. some kind of catch basin, possibly and extra pump.
