Palo Verde is a family of trees native to the Sonoran Desert. There are 3 varieties of this rugged desert native; Mexican Palo Verde, Yellow Palo Verde or Foothill Palo Verde, and Blue Palo Verde. Of the three available choices for your xeriscaping landscaping, the Blue Palo Verde is the best selection.
While the Mexican Palo Verde has visually stunning blooms that have the added excitement of one vivid orange petal on every flower, it lacks the attractive shape and size of the Blue Palo Verde. Additionally, this particular native of the Sonoran can be extremely invasive. In your Arizona landscaping – this translates to lots of weeds.
The Yellow Palo Verde, also known as the Foothill Palo Verde, is much smaller than the lovely Blue variety and very slow growing. While this selection of the desert trees is more drought tolerant than the Blue Palo Verde, it is far less graceful in natural shaping. You’ll be waiting a long time for Yellow Palo Verde to become a presence in your Arizona landscaping. It takes 100 years for these small trees of about 15 feet tall to reach maturity. Still this variety of Palo Verde trees has some lovely qualities that have a place in your Phoenix landscape design.
The blooms on all Palo Verdes are yellow, yet each has a distinct shaping. The Yellow Palo Verde blooms look something like a huge fuchsia flower, while those on the Blue variety are beautifully bell shaped. The foliage being light yellow-green makes the Yellow or Foothill Palo Verde a great Phoenix landscape design plant for added color impact in your desert landscaping. Against the green bark, the foliage is an excellent contrast and its more upright shape does make the Foothill Palo Verde distinctive from the other two varieties.
The Blue Palo Verde is the loveliest of all in this family of xeriscaping landscaping trees. The weeping shape of maturing Blue varieties is much more graceful. This native desert tree is faster growing and will reach 30 feet tall, making it an excellent small shade tree for today’s suburban yards. In bloom from May – June, the Blue Palo Verde is outstanding for floral interest and vivid yellow accents to add excitement to your outdoor living areas and curb appeal. This particular selection of the native Palo Verde does require more water than the others, but with drip irrigation your Phoenix xeriscaping will be more attractive.
Since during hot, dry months, the Palo Verde will lose its leaves, it makes a great deal of sense that adding drip irrigation to these valuable xeriscape trees’ space in your Arizona landscaping. This simple, no waste watering solution will also maintain your real estate curb appeal as any home landscape is far more attractive when trees are in full leaf and the plants are lush and vigorous. The other asset you will find in adding properly calibrated drip irrigation to your desert landscaping, is that all the plants will grow and fill faster with a little assistance from you.
