Fouquieria macdougalii (Mexican Tree Ocotillo)

This large spiky succulent occurs on rocky slopes in Sonora, Mexico from 500 to 2500 feet. Long spiny branches (canes) arise from a short thick trunk. The small green leaves that line the branches are drought-deciduous. Bright red flower clusters appear primarily in the spring, but can bloom intermittently throughout the year, attracting hummingbirds. Plant in full sun and well-drained soils.
