A Colorful Yellow April Display: Palo Verde Trees

April in the desert garden is, in my humble opinion, the most beautiful time of year for summer blooms.  Winter and spring-flowering plants (Damianita, Penstemon, and ‘Valentine’ Emu Bush) are just beginning to fade and summer blooms are beginning to appear (Coral Fountain, Lantana, and Yellow Bells).   

Clearly the most colorful event in April is the flowering of palo verde trees.  

Did you know that each species of palo verde has a different shade of yellow?  

It’s true. The differences may not be obvious unless you see them next to each other. I’ll make it easier for you and show you some examples below.

• Blue Palo Verde (Parkinsonia florida)
• Foothills (Littleaf) Palo Verde (Parkinsonia microphylla)
• ‘Desert Museum’ Palo Verde (Parkinsonia hybrid ‘Desert Museum’)
• Palo Brea (Parkinsonia praecox)

The arrival of these yellow flowers is met with delight by many and to the dismay of others. Those that like clean, pristine landscapes, without a stray leaf or fallen flower, don’t like the flowers that they leave behind.  

As for me, I like things mostly natural and the golden carpet that my ‘Desert Museum’ palo verde trees leave behind, is a welcome sight.  

A Contemporary Garden with Summer Blooms

I like the contemporary entry to the above front garden flanked by desert spoon and the columnar cardon cacti (no, they aren’t saguaros) surrounded by golden barrels, it was the majestic ‘Desert Museum’ palo verde trees that caught my eye.

Exploring the Garden’s Design

The plant palette is limited. This works well with contemporary design. The trees are pruned a bit too high. I like the flowers from the palo verde trees along the street decorating the grass and sidewalk.

My personal style is more informal. I do appreciate contemporary design and really like this pathway. I believe a better species of agave that can handle full, reflected heat without growing too large would have been better – maybe Twin-Flower Agave (Agave geminiflora) or Artichoke Agave (Agave parrying var. truncata)?  

I’m in love with the flowers. Aren’t they fabulous?

My favorite picture is one of the entryways. The ground is a solid carpet of golden yellow flowers. This contrasts beautifully with the gray-blue walls and red door.  

How about you?  Do you like the way flowers look on the ground?  Or do you feel the overwhelming impulse to blow them away?
