This is a commercially planted group of golden barrel cactus, also known as mother-in-law cushions. I know this because no self-respecting barrel would choose to grow this close to another, just like a wise mother-in-law (without the thorns)!
Barrels have a single blossom in the spring. You can see the remains here. What I like is their representation of both the short-term represented by the fading blossoms and the long-term potential of life. Living beings often grow slowly in the desert, taking time to put down roots. Under the right conditions, barrels live to be over a hundred years old.
These cacti remind me that we do not need a reason to exist–sometimes it is okay to just sit there and look beautiful.
Observe the space between your thoughts.
Then observe the observer.
