Taylor Family Desert Legume Garden

In collaboration with the Desert Legume Program at The University of Arizona, the Taylor Family Desert Legume Garden serves to illustrate the diversity and usefulness of legumes from deserts around the world. In fact, many common trees of the Sonoran desert are legumes, like the mesquite, palo verde, and ironwood.

Chihuahuan Desert Exhibit

The largest desert in North America is well represented in this collection of agaves, yuccas, mescal bean trees, and ever-bearing prickly pear cacti, a favorite of javelina. Predominantly a shrub desert, the Chihuahuan Desert differs from the Sonoran Desert in that it has much colder winters and wetter monsoons.

The Chihuahuan Desert is considered the most diverse desert in the Western Hemisphere and one of the most diverse arid regions in the world. Unfortunately, because of human activities and the overcollection of native plants and animals, it is also one of the most endangered regions in the world.

Children’s Garden

With three sensory gardens, a human sundial, and a maze, the Children’s Garden offers children and the young at heart a unique environment filled with hidden treasures.

At the heart of the Children’s Garden is the Gloria Wing-Ong Children’s Learning Center.

This ‘outdoor classroom with a view’ is named in honor of Gloria Wing-Ong, a teacher who inspired her students to discover the joy of learning. Today her legacy continues with educational programs offered year-round for children and adults.

Heritage Rose Garden

This garden, adjacent to the 1920s-era Smith Building, features heirloom or antique roses, varieties dominant during the 19th and early 20th centuries. These particular roses, by design, use less water and fertilizer, require little pruning, and are less likely to be threatened by fungus in comparison to their hybrid cousins.

Rodica Heinz Pollinator Garden

The Pollinator Garden displays a variety of seasonal plants that attract and nurture the pollinators so important to the health of our ecosystems—butterflies, bees and birds. Species include flowering trees and shrubs, and native perennials like coreopsis and blanket flower.

Sonoran Desert Exhibit & Curandero Trail

Distinguishing the Sonoran Desert, home to Boyce Thompson Arboretum, are its columnar cacti, like the saguaro, and its mild winters. It is lush in comparison to most other deserts and supports a rich spectrum of some 2,000 species of plants. This exhibit features plants native to the Sonoran Desert such as the creosote, jojoba, ocotillo, sotol, and of course, saguaro and other forms of cacti. The Curandero Trail highlights a wide array of wild medicinal plants found in the Sonoran Desert. The trail is named for traditional healers in Mesoamerican culture.

South American Deserts Exhibit

The South American Exhibit highlights plant communities within the Gran Chaco and the Monte Desert that are located approximately the same distance south of the equator as the Sonoran Desert is north of the equator. Though a hemisphere away from each other, these deserts share similar looking species of columnar cacti and other plants. The entrance features a “quincho,” a South American thatched hut, for shade.

Wallace Rose Garden

Originally part of the Wallace Desert Gardens, this collection comprises well over 100 ornamental hybrid tea and floribunda roses. Mrs. H.B. Wallace was very fond of roses and the extensive varieties available; H.B. Wallace amassed this large collection for her. The collection is located at the entrance to the Wallace Desert Garden.

Wing Memorial Herb Garden

The Wing Memorial Herb Garden contains many low-water use native and southern European herbs that thrive in the Sonoran Desert, such as thyme, oregano, dill, rosemary, lamb’s ear, comfrey and chamomile, along with many other herbs used in the culinary arts, medicinal healing, cosmetics and insect repellants.

Collecting and directing stormwater is essential for a desert garden's survival. If left unmanaged, pooling rain can damage plants and nearby buildings. Thanks to the generous support of Water Wise Arboretum donors, we now have several stormwater features around the Smith Greenhouses! It helps protect our historic buildings and guides the water to plants that need it most.

You can spot one of these water capture systems in front of the Smith Greenhouses. Arizona poppies are currently blooming inside, a living proof of its success!
