Yeah I don't think for me it works quite the way Cinta says. The pot has a shallow opening to the sky (the lip that is slightly offset). I could not possibly put the pot up to water it once it is full, it is very heavy. It will have to remain lying down.
There is a drain hole in the bottom (in what in a normal pot would be the side) so drainage is not my problem.
Lynn thank you for the offer of starts. I think those Sedums might find it a bit too hot here but you talking about them, and me looking at the listings to which you so thoughtfully provided links, reminded me that I have some plants that will work (I think).
