Chilopsis linearis: Desert Willow1

Edward F. Gilman and Dennis G. Watson 2


This native North American tree is well known in hot, dry areas where the soft, willow-like leaves and beautiful blooms are a welcome relief. Desert willow reaches 30 feet in height and a width of 25 feet, with fairly loose, open branching. The narrow leaves are 5 to 12 inches long and, although deciduous, provide no appreciable fall color change.

Use and Management

Unlike the weak wood of true willows, the wood of desert willow was used by Native Americans to craft their hunting bows. The wood has also been used for fence posts, and baskets are often woven from the twigs. It is the blossoms of desert willow that help make it so special, though, with the showy, 2- to 4-inc-long clusters of 1- to 1.5-inch-long, trumpet-shaped blooms appearing from late spring to early fall or only during the summer if rainfall is sparse. The blooms occur at the tips of the branches and on new growth. The extremely fragrant, orchid-like blooms are most often seen in shades of lavender and pink, but a white variety is occasionally found. The bees find the blossoms irresistible and a delightful honey is produced from the flowers. The narrow, 4- to 12-inch-long seed capsules that follow persist on the tree, and the seeds are quite popular with birds.

The multi-trunked, well-branched habit of growth and thick growth make desert willow well suited for a wide screen or tall hedge. Groups can be planted in a large-scale landscape for a splash of color. The tree has also been popular in residential plantings as specimens.

Desert willow should be grown in full sun and is extremely drought tolerant. While the trees will grow better with adequate moisture, they will not tolerate overwatering.

Cultivars include 'Dark Storm'—burgundy; flowers and 'Pink Star'—bright pink flowers.

Propagation is done easily by cuttings.
