Desert-Thorn

Near Quitobaquito Springs in Organ Pipe Cactus National Monument I saw a very striking shrub with ripe orange/red fruit. 
The thorn-berry, with red fruit just visible.
Closer view.
I've not been able to pin it down, but I think it may be what is known as the Arizona desert-thorn (lysium exsertum), found only in small portions of Arizona, mostly the south, and into northern Mexico. It has green tear-drop shaped leaves and lavender flowers. The flowers, of course, turn into the fruit and the one I saw was in the fruit stage with the flowers all gone.

Yellow Desert Evening Primrose

On a recent trip (early April) to El Pinacate and Gran Desierto de Altar Biosphere Reserve in Sonora, Mexico, between Sonoyta and Puerto Penasco, I encountered the yellow desert evening primrose (oenothera primiveras) right near the entrance. It is found in the southwestern U.S. (CA, AZ, NV, UT, NM and TX) and northern Mexico in desert flats below 4,500 feet. It has a rosette of green or grayish leaves that are cut into deep lobes or teeth and wavy or crinkled edges.

The flower can bloom from February to May and has four heart-shaped yellow petals which will fade to orange or red as they age.

Hedgehog Cactus - 2017

With a wet year (finally) I've been desert-bound and adding to my round of desert posts from seven and eight years ago. Hedgehog cacti are one of the stars of the desert bloom as they have brilliantly colored flowers, stay open day and night, and flower in bunches, making for spectacular photos. 

Even though comparably small, they stand out, as illustrated by the pictures that follow. 
Even though dwarfed by teddy bear cholla, the brilliant hedgehog flowers demand attention. 
Barrel cactus and yellow brittlebush, the hedgehog holds its own. 
Even in this panorama, with barrel cactus, teddy bear cholla, brittlebush and ocotillo, the hedgehog is no "where's waldo."

They tend to clump in bunches. And when those bunches flower, they are spectacular.



They are beautiful from the side, if you can get down low enough to see them from that vantage point. 

But my favorite view is inside the flower, the brilliant cone, the green pistil and the yellow stamens and the collected pollen.

Ocotillo - 2017 Rains

It has been number of years since I've spent much time in the desert. This year's rains got me excited to get out again and to see the desert in its blooming splendor. I've been out to Joshua Tree National Park twice and Organ Pipe Cactus National Park twice.

I did a post on ocotillo in 2009 and it feels like the right time again to share some photos of these wonderful desert plants that benefited from this year's rains. 
This area of ocotillo in Joshua Tree NP is probably the most concentrated cluster of ocotillo I've seen. 
The secondary leaves are out in green splendor and they are proudly displaying lots of red flowers. 
This area on the fringe of Joshua Tree is off Hayfield Road and has a nice mountain backdrop. 
The sun is catching the leaves of this ocotillo which stands out against the dark mountain backdrop. 

This water-logged ocotillo was in Organ Pipe Cactus NM during a heavy rain. 
These new, light green, secondary leaves are catching the morning sun. 

These red flowers really stand out against the dark green secondary leaves. 

The unopened flowers look like lipstick. 

As I mentioned in my 2009 post, ocotillo is one of my favorite desert plants. It was wonderful to see them beautifully green, flowering and thriving.

Buckhorn Cholla - Flowering

Seven years ago I did a post on buckhorn cholla, but none of the cholla I posted pictures of were flowering. In early April I was in Organ Pipe Cactus National Monument and the buckhorn cholla were flowering in profusion. I got lots of photos. I found three variations of colored flowers: orange, yellow and red. 
Buckhorn cholla with orange flowers.
Two buckhorn cholla: red flowers in the back and yellow flowers in front. 
Buckhorn cholla with red flowers between two saguaro cacti.
The orange flowers were particularly beautiful, especially when the setting sun light was shining through the petals.
