Just because it’s a desert doesn’t mean there aren’t wildflowers, even in late November.
Even in as dry a place as the Chihuahuan Desert there are still plenty of wildflowers. I believe that these in Big Bend National Park on November 22 were desert marigolds, Baileya multiradiata. The flowers may have gotten some protection from adjacent bushes that are just outside the picture frame and that account for the shadows on the flower heads farther back.
