Here's our wall. It's two-level -- lots of lilies (not currently blooming) above the lower wall; rhubarb, a water spigot, and our recently-relocated air conditioner above the top wall; and some thistles I haven't gotten around to pulling out at the very bottom.

We regret doing it the way we did. Not that the wall looks bad or anything like that--but we should have changed the design of the house prior to construction to have the garage extend further back in this location instead. (The wall directly behind the rock wall is the back of the third stall of our garage. We could have added a "fourth stall" there, and even had a separate back-of-the-house-access lower level outdoor storage room. Oh well.)
