I have a small strip of shady ground on the far side of my driveway that has awful soil--rocky, clay--and gets very little light, maybe an hour a day. I have worked so hard in my garden to amend the soil in so many spots. This is one area where I just don't want to have to do that. So I'm looking for something that can survive in this environment and will look nicer than weeds. Someone recommended wild ginger. Can I plant it, then forget about it in this type of soil and exposure?
