I would like some advice for plants for a new border, it is about 8ft X 30ft, quite heavy clay and has no shade. The complication is that there is a concrete storm drain not terribly far below the surface. I have had Rhodedendrons in it until recently but they never did very well and I believe it was a problem with the concrete.
I had a look round and found these plants and would like some advice on their suitability
