I posted this in the AZ forum also but it seems a little slow right now so I thought I would try here also:
We just bought a new house in Peoria,AZ (Phoenix area) and we are building a pool/spa. I live in an Alpine climate now similar to Flagstaff and have little knowledge of the desert trees and plants.
We had a well known local professional company design the landscape around the pool/spa and it looks great on paper. I wanted some shade trees because I know how hot it can get. Due to CCR limitations, we can only do trees like the Mesquite, Acacia, Mulga, Chaste, Texas Ebony, Ironwood, etc. Sonoran theme trees. Any suggestions on the poolside trees would be great. The landscaper wants to go with Cat Claw Acacia but I am not too sure about the look, its shade quality, and the thorns. He says they are clean and Mesquites are too dirty. Any suggestions would be greatly appreciated.
