10 Essential Native Trees for Southwestern Gardens (10 photos)

10. Desert Museum Palo Verde
(Parkinsonia ‘Desert Museum’)
Garden hybrid from trees native to the Southwest

With its long flowering season, dark green bark and fast growth rate, it’s easy to see why this palo verde hybrid is rapidly becoming popular with homeowners throughout the Southwest. Although not a true native, ‘Desert Museum’ palo verde is a hybrid of three native palo verde trees, showcasing the best traits of each of its parents. Three characteristics make it especially desirable compared to other palo verde species: It is thornless, has a longer bloom season and grows quickly during its first few years in the ground.

The foliage of ‘Desert Museum’ is made of tiny leaves, which create a light, filtered shade that is perfect for plants that appreciate a little protection from the sun. Like most palo verdes, this hybrid does best when trained as a multitrunk tree. Avoid the temptation to prune the canopy too high up, which can lead to weak limbs that are susceptible to wind damage. Instead, allow the lower branches to remain for a few years, which will help the lower trunks increase in size and strength.

Where it will grow: Hardy to 15 degrees Fahrenheit, or minus 9.4 degrees Celsius (Zone 8)
Water requirement: Low
Light requirement: Full sun
Mature size: 25 feet tall and wide
