Continue reading because we cover some popular varieties that thrive in desert conditions.  (1, 2)

Chaste Tree (Vitex agnus-castus)

Although native to southern regions of the Mediterranean, chaste trees make a hardy addition to a desert garden like southern Arizona.

It’s hardy growing in USDA zones 6 through 9. In the coolest portion of its hardiness range, the tree may die down to ground level in the winter but will resprout in spring. However, it grows best in an area with warmer winters.

Provided preferred conditions, chaste trees thrive in the heat, sun, and dry and arid conditions that a desert landscape offers. The tree has an average lifespan of 50 to 150 years.

Chaste trees have a vase-shaped, shrub-like nature and form multiple trunks. With pruning, the tree can be shaped into a small tree that matures at 20 feet tall and wide.

Chaste trees are deciduous in the winter. However, in the spring, the canopy fills with a 6-inch lance-shaped, grayish-green foliage that is fragrant. In summer, 12-inch long, upright panicles fill with fragrant purple flowers that make a beautiful sight rising above the canopy.

For the best performance and growth, grow the chaste tree in a site situated in full sun or partial shade. Although the tree prefers fertile soil that drains well, it’s also tolerant to drier and less fertile soils when provided sufficient water. Moderately drought-tolerant, once established, chaste tree performs best with regular and deep water applications. That being said, make sure to water weekly during the tree’s first year of growth.

Chilean Mesquite (Prosopis chilensis)

Native to South America and the Southwest, Chilean mesquite trees make attractive and hardy additions to a desert landscape. Hardy in USDA zones 8 through 11, these heat-lovers and drought-tolerant trees make beautiful additions to xeriscapes, rock gardens, and desert landscapes like those found in Texas and Arizona.

Chilean mesquite trees are semi-evergreen and develop an open and spreading canopy filled with airy green, fern-like leaves. The fast-growing desert tree grows to a mature height of 30 feet tall and wide and can live 50 to 150 years.

The grey bark is fissured, and depending on the variety, it may either be thornless or contain thorns. In spring, inconspicuous greenish-yellow flowers bloom. Once the flowers fade, they give way to long brown seed pods that attract birds. The tree also works well planted in groups where the airy canopy filters the harsh sun and reduces heat and glare.

These trees grow well in fast-draining soils that have a sandy texture and are dry. Chilean mesquite trees also grow best located in a site receiving full sun, making them great additions to a desert garden. During their first year of growth, water deeply weekly. Thereafter, the desert tree only requires occasional irrigation. However, if summer conditions are sweltering and dry, the tree appreciates more frequent water applications.

Desert Willow (Chilopsis linearis)

Native to California, Texas, Arizona, and New Mexico, desert willow is an attractive desert tree hardy in USDA zones 8 and 9.(3)

It earns its common name due to it resembling true willow trees. The small flowering tree or large shrub is tolerant of the heat and arid conditions found in a desert region, making it a great addition to a desert garden.

The native tree has a deciduous and fast-growing habit. Desert willow trees produce a single trunk that often has a twisting or leaning habit and open, low branches. The willow-like foliage is light green and grows anywhere from 4 to 12 inches long. Fragrant and showy flowers start blooming in late spring and smell like violets. Blooms are funnel-shaped and range in colors of purple to dark pink with white or yellow streaked throats.

In autumn, once the flowers fade, long and slender seed pods form. Various birds and pollinators are attracted to the flowers and seed pods. Desert willow averages around 15 to 25 feet tall and 10 to 20 feet wide, making it suitable for a small yard or landscape.

Desert willow trees thrive in various well-drained soils, although limestone soils are preferred. The desert tree thrives in dry, hot, and arid regions planted in full sun. It’s drought-tolerant and excessive water leads to weaker growth, a reduction in flowers, and problems with rot. Allow the soil to dry out between water applications to encourage more blooms.

Desert willow makes a beautiful addition to rock gardens, xeriscapes, pollinator gardens, or a sunny desert garden.

Texas Mountain Laurel (Sophora secundiflora)

A beautiful desert tree native to Texas and New Mexico, Texas mountain laurel is hardy in USDA zones 7 through 10.
