We are at 4600 feet in the southeastern part of AZ. Just put in a pool last year, and now we will have a new neighbor just behind us, on the other side of a 5 ft. block wall. Because of the slope of the land, the new neighbor (house not finished yet) will be able to see parts of our yard and patio.

I know I'm probably in a dream world, but we'd like to find some trees that:

Âgrow rather quickly and get decently tall (8-10 ft)

Âare hardy in freezing temps

Ârequire little water once established and can go with the seasons like our mesquites

Âdo not drop their leaves or make a mess (because of the pool)

Âprovide good privacy screening

Does such a tree exist?
