One of my favorite places on earth is Saguaro National Park West near the Tucson mountains. It is a truly magical place. Palo Verde trees are a nurse plant for saguaro cactus. Saguaro seeds often germinate under the tree and are protected from harsh sun and temps until the cactus is large enough to survive on its on. Thats why you often see a saguaro and Palo Verde together.
