Hi all. I need some suggestions please. I want to plant something to cover a wall that only gets sunshine for about 1-2 hours each day. The position is not in dense shade, just doesn't receive direct sunshine for most of the day. The soil at the base of the wall is, well not soil really, more like building rubble and cement! So whatever grows there will definitely need to be in a large pot rather than in the ground. I would prefer to have something that gives colour but anything that is green will do. The position is fairly sheltered (no strong winds) and the wall does have eaves overhanging so conditions tend to get dry quickly. I know ivy will probably to the trick but if anyone has something else to suggest I would welcome this as ivy is, well, not the most interesting of plants, it will be a good last resort though.
