An amazing system

Mojave Yucca #0311-1233 (12,000 years old, Mojave Desert, California)
The approximately 12,000-year-old creosote bush and Mojave yucca both have remarkable circular structures, pushing slowly outward from a central originating stem. New stems replace old ones, but they are all connected by the same clonal root structure.
