Recommendations for Phoenix and Tucson area destinations?

In what has become something of a tradition, I’m planning another trip to Arizona this December. While I never get tired of revisiting favorite haunts, like the Desert Botanical Garden in Phoenix and the Arizona-Sonora Desert Museum in Tucson, I’d like to discover destinations that are new to me. By “destination” I’m referring to gardens with interesting plants (public or private), nurseries, or sights that are beautiful in and of themselves.
