Joshua tree (Yucca brevifolia) is an iconic symbol of California’s deserts, found in the Mojave Desert and parts of Utah. This tree-like monocot, related to lilies and palms, grows at elevations from 1,600 to 6,600 feet, occasionally reaching 11,000 feet. Its stiff, dagger-like leaves and clusters of greenish-white flowers give it a striking appearance.
Joshua trees rely entirely on the tiny Tegeticula moth for pollination. The moth lays its eggs in the flowers, and the caterpillars feed on some of the seeds, ensuring mutual survival. These trees also provide nesting sites for around 25 bird species and are the host plant for the Yucca Giant-Skipper butterfly.
Due to its slow growth and specific habitat needs, Joshua tree is rarely used in residential gardens. However, it can serve as a dramatic, sculptural feature in large desert or semi-desert landscapes. When transplanted, it requires careful watering to prevent rot.
For those in appropriate climates, the Joshua tree is a low-maintenance, drought-adapted choice that supports native wildlife.
