An Arizona native desert tree with a spectacular bright yellow spring bloom and light green trunks. The blue Palo Verde is thought to have arrived in Arizona approximately 4,240 years ago, according to pack-rat midden evidence.

Blue palo verde is a drought deciduous tree, up to 30 feet tall, with a short trunk; and smooth buish-green bark. it normally is leafless, or it has temporary bipinnate leaves, 0.4 to 0.8 inch long, 1 pair of pinnae, and 1 to 3 pairs of leaflets

The Blue palo Verde needs more water than the Foothill Palo Verde and is normally restricted to washes and other areas closer to water. Blue Palo Verde usually blooms about two weeks before Foothills Palo Verde. It also is the largest of the Palo Verde.

Humans have also relied on the seeds for food; crops are abundant in most years. The Oodham preferred to eat the green seeds or pods; young seeds are tender and taste much like fresh peas. The Seri ate the fresh green seeds and also toasted, ground, and ate the mature seeds in a gruel. They usually raided pack rat nests to obtain the mature pods, and then winnowed the seeds.

Four species of palo verde grow in the Sonoran Desert and sometimes naturally hybridize.

Its name means "green stick" in Spanish, referring to the green trunk in which the tree does photosynthesis.

Official state tree of Arizona.
