OUTSTANDING FEATURES: The ‘Desert Museum’ palo verde has several unique characteristics that set it apart from other palo verde selections. First, it has an upright growth habit that allows it to be used as a walk-under shade tree. Second, the mass of flowers produced in late spring is nearly unrivaled among desert trees. Third, its smooth, light green bark is quite attractive. Finally, the amount of shade produced and the thornless nature allow for use in a variety of situations. This thornless nature is sometimes considered the most desirable feature!
CULTURE/MAINTENANCE: ‘Desert Museum’ is hardy to about 15 degrees F and possibly lower. One tree in El Paso showed no damage after experiencing a low of 10 degrees F. Once established, it is quite drought tolerant. However, the additional of supplemental water will help this tree to grow faster and flower more profusely. Be careful not to overwater, as the tops may become too heavy. ‘Desert Museum’palo verde grows best in native soil with good drainage.
IDENTIFICATION: The combination of large (for a palo verde) flowers, thornless nature,
and leaf structure set this palo verde apart from the rest.
LANDSCAPE APPLICATION: Use ‘Desert Museum’ palo verde as a fast-growing shade tree in all zones of a xeriscape. It looks as good in the mini-oasis as it does in the outer zone. This tree is well suited for full sun and reflected sun locations. The light shade cast by this tree makes it an ideal nurse plant for cacti and other succulents.
PRECAUTIONS: Take care to not overwater this tree as it may grow too fast and become top
heavy. If the top gets too dense and heavy, the roots may not be able to support the tree. Protect young trees from damage by rabbits, javelina, or deer. The bark and young branches may be eaten, causing deformation and sometimes death of the whole plant. Also, sometimes other species of Cercidium can be defoliated by butterfly or moth larvae in the spring and summer.
