I have a horrible-looking corner of my yard (very rocky and bare) and I have decided I just want to plant a huge bush there and just let it go crazy and cover the whole area. It's in full sun, very well-drained soil... and the whole area I want it to eventually cover is about six to eight feet square (well, triangular.) Height isn't a concern... but I would like it to be full all the way to the bottom of the plant, so as to cover all the rocks and ugliness.
I'm thinking perhaps a Rose of Sharon? Any other ideas?
