Blue Palo Verde Decorates the Landscape

Do you like palo verde trees?

Blue palo verde (Parkinsonia florida)

I must confess that I fell in love with these iconic desert trees with their green trunks and yellow flowers when I moved to Arizona 28 years ago.

Some people may resent the mess that the fallen flowers leave behind in late spring, but I don’t mind – they look like a carpet of yellow.

Blue palo verde (Parkinsonia florida) is on my ‘fuss-free‘ list of trees that add beauty to the arid landscape.

How about you?  Do you like blue palo verde trees?

The Best Palo Verde Tree Variety

AZ Plant Lady, Landscape Design, Trees

I don’t have a favorite tree….I actually have quite a few favorites.  But, if I had to pick one that I like most of all, it would be the ‘Desert Museum’ Palo Verde (Parkinsonia x ‘Desert Museum’).

Remarkable Hybrid Origins of the ‘Desert Museum’ Palo Verde

This Palo Verde is natural hybrid, resulting from 3 other Palo Verde tree species – Mexican Palo Verde (Parkinsonia mexicans), Blue Palo Verde (Parkinsonia florida) and Little Leaf Palo Verde (Parkinsonia microphylla) trees.

I have grown this tree in commercial settings as well as in my own landscape with great results.

Best Qualities of the ‘Desert Museum’ Palo Verde (Parkinsonia x ‘Desert Museum’)

1. Drought Tolerance

The ‘Desert Museum’ Palo Verde is renowned for its exceptional drought tolerance. This hardy tree thrives in arid desert conditions, making it a perfect choice for water-efficient landscaping.

2. Striking Aesthetic Appeal

With its vibrant yellow flowers that burst into bloom during the spring, the ‘Desert Museum’ Palo Verde is a visual delight. Its green bark adds to its aesthetic charm, making it an iconic feature in any desert landscape.

3. Low Maintenance

This desert tree requires minimal maintenance, making it an excellent choice for homeowners and landscapers looking for easy-care options. Its adaptability to harsh desert environments means less fuss and more enjoyment.

4. Fast Growth

The ‘Desert Museum’ Palo Verde is thornless and known for its relatively fast growth rate. It quickly establishes itself, providing shade and beauty to your landscape in a shorter time compared to many other trees.

5. Long Blooming Season

With a lengthy blooming season extending from late spring through early summer, this Palo Verde tree provides an extended period of vibrant yellow blossoms, attracting pollinators and adding life to your garden.

6. Wildlife Attraction

This tree attracts various wildlife, including birds and pollinators, making it an excellent choice for creating a biodiverse and vibrant ecosystem in your yard.

7. Low Water Requirements

Ideal for water-conscious gardeners, the ‘Desert Museum’ Palo Verde has low water requirements once established, reducing the need for irrigation and conserving precious water resources.

8. Heat Tolerance

It thrives in scorching desert heat, maintaining its vitality even during the hottest summer months, ensuring a consistent and appealing appearance throughout the year.

9. Pest and Disease Resistance

This Palo Verde variety is relatively resistant to common pests and diseases, reducing the need for chemical interventions and promoting an eco-friendlier garden environment.

10. Versatile Landscaping

Its versatility allows it to be used in various landscaping settings, including as a shade tree, focal point, or as part of a xeriscape design, adding both beauty and functionality to your outdoor space. ‘Desert Museum’ Palo Verdes do great in full sun and areas with reflected heat such as a parking lot or in a west-facing exposure.

A Palo Verde Tree That Rises Above the Rest

I love how beautiful flowers in spring, when they bloom.  I also think they are pretty when they blanket the ground.

If you are somewhat of a neat and tidy gardener, then you may not enjoy the flowering season as much as I do.

Don’t waste your money on a large-size tree. Because they grow fairly quickly, a 15-gallon is a good size to start out with. Once planted in the ground, a 15-gallon will grow more quickly then a larger-size container. The reason is that smaller trees are younger and handle transplant stress better.  So save yourself money and go with the smaller tree.

Flowers Raining Down….

AZ Plant Lady

This is my favorite time of year in the garden.  You may be saying, of course it is….it is spring after all.  Isn’t that everybody’s favorite time?  Well, there is another reason.  This time of year I cannot go outside without coming back inside with a yellow flower or two in my hair.

All three of my Palo Verde trees are blooming.  Each one is covered in yellow blossoms.  Actually some of the branches are hanging quite low due to the weight of the flowers.  My Palo Verde tree above, is about 4 years old and will eventually grow to be about 30 ft. tall and wide.

 ‘Desert Museum’ Palo Verde flowers

Palo Verde trees are the iconic trees of the desert southwest.  The word “Palo Verde” is Spanish for “Green Stick”, which aptly describes their green trunks.

In times of extreme drought, they drop their leaves to avoid losing excess moisture and they will continue to photosynthesize through their green trunks.  What a great survival mechanism, don’t you think?

There are quite a few different types of Palo Verde trees.  My favorite is a hybrid that was found growing in the Tucson desert near the Sonoran Desert Musuem.  Appropriately, it is called ‘Desert Museum’ Palo Verde.  

It grow very quickly, is thornless, produces yellow flowers somewhat larger then their cousins and is quite low-maintenance.

Blue Palo Verde

Blue Palo Verde (Parkinsonia floridium)

Blue Palo Verde trees are also quite beautiful and an asset in the landscape.  Their bark has more of a gray-green color and is a slower growing Palo Verde.

Palo Verde trees flower in the spring and mine sometimes flower a little in the fall, although that is not always dependable.

Palo Brea

 Palo Brea (Parkinsona praecox)

Another type of Palo Verde is the Palo Brea tree.  Their trunk is bluish green in color.  They do have thorns and must be pruned often to keep their branches from growing downwards.  But, they are absolutely lovely in the landscape.

Foothills Palo Verde

Foothills Palo Verde (Parkinsonia microphylla)

Last, but not least, are the Foothills Palo Verde, which grow very slowly, but have beautiful branch architecture.  This is the type of Palo Verde that you will find growing out in the desert most often.

Lately, every time I come back inside from the garden, I find a flower or two that has fallen into my hair. 

Did I mention that I love this time of year?

Iconic Desert Tree, The Palo Verde

When people think of the Sonoran desert, hillsides studded with saguaro cactus and cholla often come to mind.   But interspersed between the cactus, you will find the palo verde, an iconic tree with their beautiful green trunks and branches.

An Iconic Desert Tree; The Palo Verde

The word “Palo Verde” means “green stick” in Spanish, referring to their green trunk, which is a survival mechanism in response to drought.  

Palo verde trees are “drought deciduous,” which means that they will drop their leaves in response to a drought situation.  Their green trunks and branches can carry on photosynthesis, even in the absence of leaves.

Palo Verde Trees Are Nurse Plants to Saguaro Cacti

Palo verde trees act as a “nurse plant” to young saguaro cacti by protecting them from the cold in the winter and from the intense sun in the summer.  Beautiful, yellow flowers are the product in the spring.

There Are Several Species of Palo Verde

There are three species of palo verde that are native to the desert Southwest; blue palo verde (Parkinsonia florida), formerly (Cercidium floridum), foothill palo verde (Parkinsonia microphylla), formerly (Cercidium microphyllum) and ‘desert museum’ palo verde (Parkinsonia x ‘Desert Museum’).

Another species of palo verde that is prevalent in the landscape are called palo brea (Parkinsonia praecox), formerly (Cercidium praecox).  They have a dusty green trunk and branches that twist and turn.  Their cold hardiness range is around 15 to 20 degrees F.

Palo Verde Landscape Uses

Palo verde trees serve as beautiful specimen trees where their green trunks, branch structure, and flowers serve as an attractive focal point in the landscape.  They are drought tolerant, once established and provide lovely filtered shade year-round.  

When deciding where to place your tree, be sure to take into account that they need a lot of room to grow, mature sizes are listed below.  

Palo Verdes don’t do well when planted in grass and will decline over time.  Locate away from swimming pools due to flower litter in the spring.

Because of their more massive thorns and branching tendency to point downwards, palo brea trees aren’t recommended in areas close to foot traffic.  

Mature Sizes:

  • Blue Palo Verde – 30 ft x 30 ft
  • ‘Desert Museum’ Palo Verde – 30 ft high x 40 ft wide
  • Palo Brea – 30 ft x 25 ft
  • Foothills Palo Verde – 20 ft x 20 ft

As with many desert trees, Palo Verde trees have thorns, except for the ‘Desert Museum’ Palo Verde.

Basic Palo Verde Maintenance

Pruning for Canopy Elevation and Structural Integrity:

Pruning Palo Verde trees in your desert Southwest garden is a crucial aspect of maintaining their health, aesthetics, and structural integrity. One of the primary objectives of pruning is to elevate the canopy, ensuring it remains well-balanced and visually appealing. This practice involves selectively trimming the lower branches to create a more elevated and open canopy. By doing so, you allow for better air circulation and light penetration, which can promote overall tree health and reduce the risk of disease.

Steering Clear of Hedging and Topping:

While pruning is essential, it’s equally vital to understand what not to do. Avoid two harmful practices: hedging and topping.

  1. Hedging: Hedging involves indiscriminate shearing or cutting of branches to create a uniform, artificial shape. This practice is highly discouraged for Palo Verde trees, as it not only compromises the tree’s natural beauty but also disrupts its growth patterns. Hedging can lead to dense, bushy growth with weaker, more susceptible branches.
  2. Topping: Topping is the severe cutting of the uppermost branches, often leaving stubs or bare trunks. This practice is detrimental to the tree’s health and stability. When Palo Verde trees are topped, they respond with a vigorous burst of new growth that tends to be weak and prone to breakage. Topped trees are also more susceptible to pests and diseases.

The Proper Tree Pruning Approach:

Instead, adopt a thoughtful and strategic approach to pruning your Palo Verde trees. Start by identifying dead, diseased, or damaged branches, and promptly remove them. This eliminates potential entry points for pests and diseases, promoting tree health.

Next, focus on elevating the canopy by selectively pruning lower branches. When selecting branches for removal, prioritize those with narrow crotches or those that cross and rub against each other, as these can weaken the overall structure.

Consider hiring a certified arborist or a professional tree service to ensure that your Palo Verde trees receive the care they deserve. These experts have the knowledge and experience to prune your trees correctly, preserving their natural form and promoting robust, healthy growth.

By following proper pruning practices and avoiding hedging and topping, you can help your Palo Verde trees thrive in your desert Southwest garden. A well-maintained Palo Verde tree not only adds to the beauty of your landscape but also provides valuable shade and habitat for local wildlife while remaining resilient in the harsh desert environment.

Palo Verde is My Favorite Tree

As a landscape manager, horticulturist and arborist, I have grown and maintained all of the palo verde species mentioned, and I truly enjoy them all.  However, at home, I have 4 ‘Desert Museum’ trees. 

In comparison to the other species, their trunks are a deeper green; they produce larger flowers, are thornless and grow very quickly in the desert.  Also, they require little, if any, tree staking when planted. Simple amazing!
