Ok, at long last, I can share some pics with you guys of the project that basically started last year when we got a microburst that wrecked my garden with hail and took down a large pine. Several kind DG'er sent me hosta to use in a new bed that would be where the tree fell. Unfortunately, getting the tree out of there took all of the summer and into the fall, so the bed had to wait to be built til this Spring.
I designed it with two tiers to go up the slope. Because I have neither the money to buy lots of stones to build the walls, nor the talent or patience to stack them all nice and secure, I devised a plan to make my own faux rocks using a foam covered concrete block I cast, and then used hypertufa on the face to carve the "rocks". I just wanted it to blend in with the other areas of natural stone, which I think it does nicely. It took a while to figure it all out, but I'm happy with it, though it's not entirely done.
Here is a pic from last year, with the fallen tree. It was massive.
