Best Heat Tolerant Shrubs for Desert Landscapes

Shrubs can be very low maintenance, often permanent additions to the landscape. Shrubs are like big, bold perennial plants that get better year after year. You will find the summer selection of plants at the garden center like heat, sun, and drought, better than their spring cousins. For better color, fragrance, and beauty, start with this list of top plants for local landscapes.

Barberry is not picky and tolerates most soils, wind, and heat levels. Barberry can go in any direction in terms of height and appearance and is low maintenance and ideal for hedges. Plant this shrub in at least 6+ hours of sun with minimal pruning or upkeep.

Butterfly Bush is locally named the summer lilac. The fruity fragrance with incredibly showy flowers is a summer magnet to both butterflies and hummingbirds. It is easy to grow with many new dwarf varieties that only grow to hip height for even easier maintenance and care.

Cotoneaster has many varieties, including ones that creep and trail. Red Cluster Berry can reach 10′ feet tall with an impressive spread. Coral Beauty spreads wide 10′ and under knee height. All cotoneasters bloom white in spring, take the summer heat, and a stunning red berry that often lasts through winter. This variety of plants is impervious to deer, rabbits, and javelina.

Crape Myrtle has intense summer blooms in watermelon-pink, solar red, and LED white from summer through fall. Use as an accent or to cover unattractive views on a small scale. The best flowers are enjoyed close up, where you can enjoy its beautiful multicolored bark and sinuous branches. The flowers are striking against forest green foliage that turns red and orange in Autumn. Growing to just head height, every yard has room for at least one.

Juniper includes everything from ground creepers to tall evergreen trees. They are excellent hedge plants, growing into perfect shape without pruning and shaping. Juniper is so flexible it can be planted in the yard, containers, or raised beds. Irrigate the first couple of seasons to establish, then let them go in a xeriscape fashion. Deer, rabbits, and javelina proof.

Potentilla is on the smaller side, growing only knee height with dainty yellow flowers spring through summer. It grows slowly but heartily, establishing itself even in poor clay soil. Sun is an essential key making it an excellent choice where heat-tolerant shrubs and plants are necessary. Deer, rabbits, and javelina proof.

Spirea is another gorgeous flowering shrub spreading out in a fountain of pink or white clusters of blossoms. It continues to thrive through the summer heat, culminating in orange autumn foliage. Varieties range from 2 to 6′ feet tall and wide. Choose the type that best suits your space and enjoy easy maintenance with attractive returns. All spireas are both deer and javelina resistant.

Rosemary is medicinal, culinary, fragrant, and functional. Rosemary is a year-round favorite that fits equally well as a landscape shrub as it does in the herb garden. The fragrance repels insects, snakes, deer, and javelina with the daintiest blue flower in spring.

Roses come in all shapes, sizes, and colors, providing fun garden projects. Mix and match varieties for an eye-catching look. Old gardeners’ tails say to put a nail in the ground with the new plants to help provide minerals. Harvest the hips at the end of the year for delicious organic rosehip tea. Whether Hybrid Tea, Floribunda, Shrub, or Groundcover, all roses need at least 6+ hours of sun to bloom well.

Sumac is an excellent shrub for heat and wind that also repels insects. With prevention as the best medicine in the organic garden, this is an important quality. After the summer sun has cooled, sumac’s blazing red foliage steals the Autumn show. Deer, rabbits, and javelina proof.
