A very striking succulent shrub, up to 25 feet (7.6 m) tall and up to 10 feet (3 m) wide. Branches are smooth, cylindrical, green, about the diameter of a pencil. Branch tips are orange, red, or pink. The color tends to fade closer to yellow in the summer and becomes redder in the winter. There are no spines. Leaves are small, about 0.5 inches (1.3 cm) long and less than 0.12 inch (3 mm) wide. They fall off early, so usually, the stems appear naked. Flowers are pale yellow and inconspicuous.
