A hybrid of several palo verde species, the Desert Museum variety combines the best traits: thornlessness, fast growth, drought tolerance, and prolific blooming. Its sculptural form and vivid spring display make it a centerpiece in Phoenix Valley landscapes.

General Watering Tips for Desert Museum Palo Verde

• Soil Check: Water when soil is dry 4-6 inches deep.
