Hello little Lady, and welcome aboard the Banana Express.
I have been all over this wonderful nation of ours, and Arizona is one of my most favorite places to visit.
There is a nursery, heading toward Phoenix on Baseline, that has almost everything you'll need in the Valley area. It's on the left. I don't remember the name, as it it was 2000 when I was there, but if anyone can set you up, it'll be them.
