Desert plants often look timeless, and some nearly are. Chris Clarke explores the astonishing longevity of desert vegetation, from the roughly 11,700-year-old King Clone creosote ring to chollas and Mojave yuccas that can survive far longer than their appearance suggests. He also explains how researchers estimate plant ages when tree rings aren't available, using historical photographs, repeated observations, and long-term ecological studies. The result changes the way we see seemingly ordinary plants: some desert landscapes contain living organisms whose histories stretch back centuries or millennia.
