The Blue Palo Verde is Arizona’s state tree, and worthy of planting in your Tucson and Green Valley area home landscape.
This species of Palo Verde is a hardy, drought tolerant native, with lovely green bark and blue-green leaves. The yellow spring flower show is stunning. This is a considered a fairly large tree, although slow growing, it will eventually reach 30 feet tall and wide.
Plant the Blue Palo Verde in well-drained soils and full sun or reflected heat. Unlike the Mexican Palo Verde, this tree is rarely bothered by the Palo Verde borer.
The Blue Palo Verde makes an excellent specimen tree because of its sculptural shape. When selecting, pick a multi-trunked specimen since that will provide more interest. Remember that buying a larger tree does not necessarily mean a better buy. Smaller trees establish quicker, and usually do not require staking. This is important as staking trees is over-done, and often leads to weak trees and poor growth.
