The living rock cacti is a close cousin to peyote, and it’s found only in the Big Bend region of the Chihuahuan Desert. It has no thorns and is soft and plushy. It’s highly sought after for collectors, and has been subject to poaching and smuggling. This specimen is estimated to be around 30 or more years old. This one can’t be placed back into the wild because wildland managers don’t know what subpopulation it’s from, so it’s staying at Sul Ross University until it gets a forever home.
