Cholla in the Desert

 Cylindropuntia fulgida or Hanging chain cholla or jumping cholla

Cylindropuntia fulgida, also referred to as the hanging chain cholla, is a remarkable cactus native to the Sonoran Desert and the Southwestern United States. Its greatest range encompasses nearly all of Sonora, except for the Sierra Madre Occidental cordillera on the east, and extends into northern California. In the Southwestern United States, you can find it in the Colorado Desert of California and various locales in Arizona. It even ventures into the Mojave Desert in southern Nevada and Utah, as well as the Great Basin Desert in southern Utah. The jumping cholla thrives in arid environments, where it forms striking forests of interconnected plants spanning vast areas1.

The jumping cholla is an arborescent (tree-like) cactus with a low-branching trunk. Its stems are light green, tuberculate (covered in wart-like projections), and measure 6 to 9 millimeters in length. These stems give rise to drooping branches adorned with silvery-yellow spines, which darken to gray as they age. The spines form a dense layer, obscuring the stems and creating an otherworldly appearance. As the spines fall off from older parts, the bark reveals a rough, scaly texture. The jumping cholla blooms in mid-summer, displaying white and pink flowers streaked with lavender. Interestingly, it opens its flowers precisely at 3:00 p.m. solar time, a quirk noted by naturalists1.

Cylindropuntia fulgida grows at elevations ranging from 300 to 1,000 meters (980 to 3,280 feet). While the name “jumping cholla” specifically applies to this species, it is also used more broadly for all chollas. The plant can reach heights of up to 4 meters (13 feet) and forms dense, sprawling clusters. Its cylindrical trunk holds multiple low, drooping branches, creating a distinctive silhouette. Beware of those spines—they detach easily and seem to “jump” onto unsuspecting passersby. So, if you encounter a jumping cholla, admire its unique beauty from a safe distance.
