Before and after - the cactus wall

I like a good before and after picture set, and here's one of the cactus wall. On the left is the before aspect. taken in February 2009. The after pic, on the right, was taken yesterday - almost 2 and a half years later. So much has changed, as you can see. The Aloe nobilis hedge has really grown in. The Yuccas are established, and completely surrounded by all manner of cool succulents and so on. I think it's my favorite part of the garden!
