The cholla garden lies lower and warmer than many Joshua-tree forests. That change marks the transition toward the Colorado Desert portion of the park.
Teddy-bear cholla look soft from a distance because dense spines reflect light. Up close, the barbed spines are an efficient defence and can detach stem segments that then root elsewhere.
The garden demonstrates why “desert” is too broad a category. Elevation, temperature and rainfall patterns create different plant communities within the same park.
Driving between Joshua trees and cholla is therefore an ecological transect. The plants are not randomly distributed scenic props. They map climate and elevation across the landscape.
