I am working on that too

@cjmoe, there are many plants that attract both butterflies and hummingbirds. Milkweed for the monarch butterfly, that is all they eat btw. Just about anything that blooms for hummers. Call your local nursery depending on where you live in Mesa. A&P on Baseline, just west of Lindsay is a good one as well as Treeland on Arizona Ave., south of Guadalupe. Or Whitfill's, if there is one in your neck of the woods.

Phoenix Home and Garden magazine have a website and should have a listing there as well. Every month there is an article for gardening and the different plants to buy.

AZ is a state that is divided into 5 different "hardiness zones". Mesa is in zone 9a. Scottsdale is in zone 9b. Select plants that are labeled for your area will help insure they can survive thru winter cold spells.
