Other Details:  The Cercidium x ‘Desert Museum’ hybrid is a gorgeous, thornless tree that makes a fine, upright shade tree. Tiny green leaves create an airy canopy, which produces filtered shade underneath. Large yellow blossoms of the Desert Museum give a dazzling display of color in the spring, lasting longer than any other in the species. It may re-bloom in summer if given supplemental water. After the foliage falls, the beautiful green trunk and stems remain green, providing year-round interest. The Desert Museum also produces very few seedpods. The Cercidium ‘Desert Museum’ has the best attributes of its three parents — Mexican Palo Verde, Parkinsonia aculeata, Blue Palo Verde, Parkinsonia floridum and Little Leaf Palo Verde, Parkinsonia microphyllum. With its bright green trunk, larger flowers, thornless branches and a more upright growth habit this tree is becoming a favorite in the California landscape.
