I suggest perusing the University of Arizona’s publications site. Lots of scientifically based resources, many free, some for sale. Here you’ll find comprehensive lists of dryland plant species, including those that are pest and wildfire resistant, lists of invasives, and seed sources: http://cals.arizona.edu/pub Also try Judy Mielke’s book, ‘Native Plants for Southwestern Landscapes’, which includes selections for all three deserts in the U.S.
