Buckhorn Cholla

buckhorn cholla blooms
Buckhorn Cholla (Opuntia acanthocarpa) blooms seen yesterday afternoon. The blooms vary in color. I’ve seen yellow, yellow/orange, yellow/red, and orange/red. The bloom in this photo was about 2 1/4 inches wide. The name Buckhorn comes from the antler-like appearance of the cactus. Antlers full of thorns!

So why is Chris touching it?! This second photo was taken at the first sign of new growth. The brand new growth is actually soft and pliable and is the only time you would be able to touch it and not leave with a spine in your finger.

Cheesebush

Hymenoclea salsola
The more common name for Hymenoclea salsola is Burrobrush but it’s also called Cheesebush because of the cheese smell you get when you crush the foliage. I didn’t know this when I shot the photo so I’m eager to go back and try it 🙂

The shrubs were spotted in the Cholla and Granite mountain area. For more information including how they were used by native peoples, click on the following link: Hymenoclea salsola

Acourtia wrightii

acourtia wrightii
The most exciting find (thanks Chris!) this weekend was Acourtia wrightii commonly called Brownfoot or Perezia. The leaves and flowers looked almost identical to the Desert Holly I photographed last year but this plant was 2-3 feet taller. As it turns out, they are of the same genus: Acourtia. The dwarf version is Acourtia nana. This one and another were spotted on the Preserve near Brown’s Ranch. One was at the base of a Catclaw (ouch) and the other at the base of a Palo Verde.

The next day, we hiked the Cactus Trail at Granite Mountain and found several large specimens out in the open. Some were just starting to bloom and some were in full bloom as shown in the photos below.

Delphinium parishii

Delphinium parishii/desert larkspur
I went to shoot Ocotillo blooms late yesterday and found this on the trail instead! I’m pretty confident that it’s a Paleface Delphinium (Delphinium parishii). It’s also called a Desert Larkspur. The flower is really interesting and reminded me a little of a Columbine because of a backward facing spur. I don’t know if this Delphinium is rare but it sure was exciting to see! (Cholla Mountain area)
