Baja Elephant Tree (Pachycormus discolor): A Sculptural Succulent Tree from Mexico

The Baja Elephant Tree, also known as Elephant Tree, Copalquín, or Torote Blanco, is a remarkable succulent tree endemic to the Baja California peninsula and parts of Sonora, Mexico. Its scientific name, Pachycormus discolor, reflects its thick, swollen trunk (pachy- = thick, cormus = trunk) and the contrasting colors of its bark.

Unique Appearance

This slow-growing tree develops a massive, bottle-shaped caudex that can reach several feet in diameter, storing water for prolonged droughts. The bark peels in thin, papery sheets, revealing a patchwork of white, gray, and green tones. During the dry season, it is often leafless, showcasing its gnarled, sculptural branches. After rains, it produces small, pinnately compound leaves and clusters of tiny, cream-colored flowers followed by small, winged fruits.

Habitat and Cultivation

In the wild, it grows on rocky slopes and canyon walls in the Sonoran Desert. In cultivation, it requires extremely well-drained soil, full sun, and minimal water—especially in winter. It is frost-sensitive and best kept above 30°F (-1°C). Its striking form makes it a prized specimen for collectors of caudiciform plants and desert gardens in warm climates.
