Unlike temperate deciduous trees which drop their leaves in response to the changing of the seasons, palo verde drop their leaves in response to drought.

Palo Verde Trees
Palo verde (botanical name: Parkinsonia) is a small group of flowering trees that grow in hot climates. The large palo verde shrubs or small trees grow between 16 and 40 ft. (5 – 12 m) high. The heat-tolerant trees are classified as a “ dry season deciduous tree ,” meaning their leaves drop when the ground is parched.
Foothill or Yellow Palo Verde (Parkinsonia aculeata)
Also called the Mexican palo verde, the attractive yellow palo verde is identified as an upright branching tree with yellowish-green leaves and pale-yellow spring-blooming flowers. Sometimes soft seed-filled pods appear on the tree. Like all palo verde trees, the foothill palo verde tree has characteristic green bark.
Blue Palo Verde Tree (Parkinsonia florida)
The stunning blue palo verde tree is a fast-growing multi-stemmed tree with gray-green leaves, small bright yellow flowers, and large, hard seed pods. This ornamental tree has bluish branches and twigs, which perform photosynthesis. Compared to the foothill tree, the blue palo verde is larger, growing 33 – 40 ft. (10 – 12 m) high.
Palo Verde Tree Leaves
Palo verde leaves are identified as pinnate leaves consisting of several small oval or linear leaflets. The small green or bluish-green leaves grow on thorny branchlets that measure 6” to 9” (15 – 23 cm) long. The small palo verde leaves help prevent moisture loss from the plant during droughts.
Palo Verde Tree Bark
Bark on palo verde trees is the most distinctive identifying trait of this desert tree. The bark covering the palo verde trunk, branches, and limbs is a unique green color. This characteristic allows the plant to photosynthesize even when there are no leaves. In addition, the green bark is smooth with horizontal grayish lenticels.
Palo Verde Tree Flowers
Flowers on a palo verde tree are stunning bright-yellow showy blooms with five papery petals, orange speckles and distinctive orange or red stamens. When the ornamental trees are in bloom, the sparse crown transforms into bright yellow soft puffs. The large yellow flowers bloom in late spring and sometimes again in late fall.
Palo Verde Fruit
Fruit from the palo verde tree is clusters of leathery seedpods, each containing two or more seeds. The light brown, red, or green pods contain large black or brown edible seeds with a sweet-pea taste. The easily identifiable pods look like beaded chains dangling from bare branches.
Blue Palo Verde

Rather than start from seed, many people like to grow their Palo Verde tree using a cutting from a pre-established tree. Growing Palo Verde trees from cutting isn’t possible, though. There’s nothing you can propagate from the Palo Verde, meaning you have to start from seed. Palo Verde seeds naturally grow in seed pods.
Do you need fertilizer for a Palo Verde tree?
Fertilizer isn’t often necessary for Palo Verde trees but will support healthy growth. Try giving your young Palo Verde tree fertilizer high in phosphorus. This will help the roots develop and grow. Once the tree is grown and established, you can stop fertilizing it altogether.
What is Palo Verde?

IDENTIFICATION
Palo Verde, Spanish for “green pole” or “green stick,” are so named because their trunks and branches are green. In Arizona there are two native Palo Verde species: the Foothills Palo Verde and the Blue Palo Verde. In the desert, Foothills Palo Verde are found on rocky slopes, while Blue Palo Verde tend to grow along arroyos, or washes.
PALO VERDE IN THE URBAN LANDSCAPE
Foothills and Blue Palo Verde are often found in urban landscapes due to the striking colors of their bark and bloom, and their amazing drought tolerance. In early spring, the combination of their bright yellow blooms against their green trunks makes a beautiful addition to any home or neighborhood landscape.
PALO VERDE TREE PLANTING RECOMMENDATIONS
Both species of Palo Verde are great trees for the urban landscape and will grow quickly when given supplemental water from a rainwater-harvesting basin. The Blue Palo Verde tree has larger leaves than the Foothills Palo Verde, but both can become great shade trees as they age.
PALO VERDE HARVESTING BASICS
HARVEST: Like other leguminous desert trees, both species of Palo Verde produce edible flowers and seeds (but many find the Foothill seeds to be sweeter). The trees generally flower in late April through May and then set green seed pods a few weeks after. The green pods will dry in June-July.

What is the disease of blue palo verde?
Witches broom disease of blue palo verde ( Parkinsonia florida) has become very common in southern Arizona landscapes. Blue palo verde is a native and the state tree of Arizona. It is very popular in urban landscapes due to its striking green-colored trunk and branches, spectacular yellow flowers in spring, fast growth rate, and excellent performance in the arid climate. Brooms are characterized by clusters of dense, short branches with leaves and without thorns and can be found throughout the tree canopy. Some trees have no brooms when transplanted into the landscape and others are composed almost entirely of brooms, giving the canopy the appearance of a dense shrub.
Is there a cure for witches broom in Palo Verde?
There is no cure for witches’ broom in blue palo verde. Our current project goals are to assist nurseries in producing virus-free and broom-free blue palo verde trees to reduce the source of virus in trees that are transplanted into landscapes. We are testing whether seeds from blue palo verde that is collected from broom affected shoots will result in seedlings and trees that are infected with the virus. We are also testing whether the use of miticides to control eriophyid mites on tree seedlings will prevent witches broom disease in the nursery.
Can witches brooms be transmitted to blue palo verde?
Asymptomatic blue palo verde plants that show no symptoms of witches broom can still carry the virus and if eriophyid mites feed on those plants, they can potentially transmit the disease to the next plant they feed on.
