I'm going to try to plant a dry garden up on the slope by the privacy fence in my apartment's front yard. The slope is pretty steep, and would be a pain to terrace, so I figured I would put only plants that, once established, can live on what nature gives them. The spot is west-facing, but really doesn't get that much sun, and is shaded by trees and a 2-story building, and the fence, in the morning. These are some of the plants I have that seem to thrive on neglect. Please make any other suggestions you want.

Oh, the spot can be up to 30 feet long if I want it to be. I'm shooting for 24 feet right now, because I only have that much in boards to border it to keep the yard crew from whacking it down..
