Candelilla (Euphorbia antisyphilitica): A Leafless, Wax-Producing Shrub for Extreme Heat

Candelilla is a unique, leafless shrub composed of dense, erect, cylindrical, gray-green stems coated in a thick layer of wax. It forms a rounded clump 2–3 feet tall and wide. Tiny, inconspicuous flowers appear at stem tips after rain. The wax (candelilla wax) is commercially harvested for cosmetics, polishes, and food additives. Native to the Chihuahuan Desert of Texas and Mexico, it thrives in the hottest, driest conditions.
