Trailing plants for retaining wall.
I have 60' of retaining wall that I would like to be covered with a trailing vine or plant. The wall gets full sun and I must plant at the top, hence the need for a cascading or trailing vine/plant. I have a soaker hose running along there so water isnt an issue. I would prefer something perennial that flowers. I have purple winter creeper on the top of it, but its not trailing down the sides like I had joped. Any ideas?
