If it is Salsify, the flower will open today and be a seed head by tomorrow. It happens just that fast. The slightest breeze will send all the seeds floating off across the desert. Salsify has a long tap root but is easy to pull.
My mother used to scout them out in the evening and then early the next morning, she would be out with her hairspray spraying the poof balls. After the hairspray dried, she picked them and used them in dried flower arrangments. Her grandchildren, who accompanied her on these trips, were confused but delighted with the entire process.
