A while back, we finally finished reworking our backyard, one of those 3 month projects that eventually threaten to be a multi-generational saga. We turned our existing pool, with a bit of trickery, into a zero-edge thing, put a dark bottom in it and ended up with a nice effect. I probably could have posted it upside down and no one would have been able to tell the difference. The pool design creates a surface like glass.
The tree is an ironwood. A lot of the more interesting plants will not grow in the desert, but an exception is the native ironwood tree. We have three now and every one is a work of art.
