Desert Willow is not a true willow, but its graceful linear leaves have the appearance of a willow. Despite this tree’s willow-like leaves, its orchid-like flowers show its catalpa origins. This long-blooming, sturdy desert tree attracts hummingbirds to its lovely flowers, and uses very little water in your yard. Our desert tortoise LOVES eating the flowers, which bloom until he returns to his den for hibernation each fall.

Desert Willow is a fast-growing, multi-trunked tree or large shrub that twists and leans as it reaches skyward, creating an interesting, open crown in age. Its long, narrow, bright green leaves give a willowy appearance, but this deciduous tree is actually a catalpa. Orchid-like, nectar-rich flowers attract bees, hummingbirds, and butterflies, and are followed by long, tan seedpods, which persist on the branches throughout winter dormancy. Ruffled, funnel-shaped flowers range from white to dark pink to burgundy, depending on the cultivar (pale pink in our local natives). Tolerates extreme heat and drought, but appreciates some summer water up to twice monthly. Great for sites where you need summer shade, but want winter sun, such as on a south-facing side of your home. Train into a shade or specimen tree with single or multiple trunks, or direct its growth as a large shrub with many branches as a windbreak, screen, or background planting.

Jojoba, Goatnut
Simmondsia chinensis

- Water Use: Extremely Low
- Mature Size: 6-8 ft. tall x 8-10 ft. wide

Jojoba is a long-lived, slow-growing dense evergreen shrub that is one of our most drought-tolerant, heat-tolerant native plants. Thick, leathery leaves grow upward so that only their edges face the sun during the hottest part of the day, reducing heat gain and moisture loss from leaf surfaces. Non-showy flowers on female plants produce acorn-like fruits containing a liquid wax prized as a stable lubricant for industrial applications, and for cosmetic and scalp preparations. Male and female flowers grow on separate plants, so fruits only develop on female plants with male plants nearby. Although wind-pollinated, bees collect pollen from male plants. This undemanding shrub has no pests, needs no maintenance, and requires no added water after it is established. Young plants may be cold sensitive, but mature plants are cold hardy. Jojoba’s dense foliage is perfect for screening or informal hedges. Great in naturalistic landscapes, in mixed plantings, or as a specimen.

Honey Mesquite should be called the “giving tree” for its abundant gifts to wildlife, humans, the soil, and the environment. Its nutritious seed pods have fed wildlife and people for millennia, its bacterial root partners add essential nitrogen to the soil, its branches provide habitat to countless animals, and its pollen is made into delicious honey by bees.
Honey Mesquite
Prosopis glandulosa var. torreyana
- Plant Form: Deciduous tree, shrub
- Water Use: Low
- Mature Size: 15-25 ft. tall & wide
- Exposure: Full Sun
- Bloom Time: Spring (Mar-May), Summer (June-Aug)

- Hardiness: Cold hardy to 0°F
Honey Mesquite is a graceful, winter-deciduous tree/shrub with multiple trunks and feathery leaves that provide cool, filtered shade from spring to fall. Yellow catkin-like flowers in spring produce nutritious, tan, pea-like seed pods in late summer that have been made into sweet flour and cakes for millennia. Bees make delicious honey from the flowers, and bacterial root partners fix nitrogen, enriching the surrounding soil. Stems develop long, paired thorns, especially on young branches. Water deeply and widely under the outermost branch tips to encourage a deep, extensive root system that can secure trees in strong winds. With its broad, rounded, weeping habit, this architectural tree is worthy as a focal point in both high and low desert gardens. Use in natural groupings to shade and cool patios and porches, or as a specimen tree.

Mojave Desert Sage is an aromatic, native “shrublet” with striking blue-violet flowers that emerge from purplish, ball-shaped flower heads along the stems. This compact, herbaceous perennial is impervious to rabbits and deer, while enticing all types of bees, pollinators, butterflies, and hummingbirds. A compact, moderately fast-growing sub-shrub, this gem of a plant has a wonderful minty aroma, released when the silver-gray, spoon-shaped leaves are rubbed. This evergreen plant usually spreads wider than high. Mojave Desert Sage is a heavy bloomer that loves the hottest, most challenging sites in your yard. Trim off seed heads and lightly prune to shape after flowering. While more water results in more flowers, be careful not to water in summer. This mint-family treasure can be used for borders, accents, bank stabilization, and in gardens designed for butterflies, hummingbirds, bees, and birds.

It’s hard to believe that this lush plant hails from our dry deserts. In days past, Basketbush Sumac was prized for its long, straight, flexible branches for basketmaking. Today it is treasured for its dense, dark green foliage for hedges, background plantings, or screens in water-wise southwest gardens. Birds also love the ripe berries produced on female plants.
Basketbush Sumac, Fragrant Sumac
Rhus aromatica

Basketbush Sumac is a surprisingly lush plant to be found in dry desert habitats. It is a tidy shrub with arching stems and dense leaves, spreading by rhizomes to form a thicket. This extremely cold-tolerant plant is a non-irritating, non-poisonous relative of poison oak, which it somewhat resembles. Known as Basketbush Sumac for its traditional use in basketry, it is also called Fragrant Sumac due to the scent of its crushed leaves, and Three-leaf Sumac from its leaf shape. This moderately fast-growing California native has tiny, yellowish flowers in spring, producing clusters of red fruits on female plants, while retaining its deep green foliage all summer. Leaves often turn orange or red in autumn before falling for winter dormancy. The tart, edible red berries (actually hard drupes) are eaten by birds. Use this tough, lovely plant for borders, screens, windbreaks, hedges, mass plantings, on slopes, or in any areas with poor, dry soils.
This beautiful evergreen perennial is very drought-tolerant and surprisingly rabbit-resistant. It blooms profusely with stunning purplish-blue flowers that are great in cut bouquets. You can’t have too many of these plants in your rock garden, borders, slopes, or containers.
