Either Phoenix canariesis or Phoenic dactylifera (my favorite). Go for Chamaerops humilis as it is good for smaller properties. You can also try Brahea armata. These are all desert plants.

There used to be some nurseries over on Baseline Dr, south of I10.

You should try a Butia capitata. They are cold hardy (not that I have that problem), beautiful and edible!

Lots of people try bismarckia nobilis with good results.

Aren't there any watering restrictions in AZ? I would think desert species would be a better suggestion.

As someone who is appalled at the waste of water in that city, apparently not.

I think all of the species mentioned are fairly low water users. To survive in the desert in the first place I think they would have to be but stick to the silver form of the bismark, not the green jungle variety.
