Answer: Tropical plants thrive with more soil moisture and humidity than we have here in the low desert. Bananas will grow here, but they require a fair amount of input from the gardener. They need a protected location from hot afternoon sun, such as an eastern exposure, as well as protection from drying winds, and regular water. There is a subtropical fruit growers group that meets at the County Cooperative Extension office once a month, and they have a demonstration garden with some unusual tropical fruits. I think you can find more info about them at this website under Garden Clubs: http://ag.arizona.edu/maricopa/garden/.
