BK,
Yep, I agree, my old house(s) in Tucson and Phoenix were studies in Xeriscape... some were studies in ZERO-scape (ha ha). Gotta love the pebbles and rock landscape.... Keeping the weeds at bay was a chore. My only thoughs are to keep with indiginous flora. I'm partial to cacti since I have the black thumb curse....
I could probably kill a rock if I tried.
