Desert Plants

Jump to: Flowering Plants  |  Cactus  |  Trees

The diversity of Arizona’s desert plants is as staggering as it is beautiful. Throughout Arizona’s deserts, the local flora is designed to thrive in an arid, unforgiving environment. With that design, comes thorns, spines, and absolutely gorgeous colors. Beans, fruits, pods, and of course, a multitude of flowers adorn this literal smorgasbord to ensure desert wildlife is kept well fed amid a sea of visually stimulating desert vegetation.  For the sake of organization we will break these desert plants into three categories; Flowering plants, cactus, and trees. Check out the desert plants list below and then plan a trip to an Arizona state park to enjoy the diversity found there!
