21 Best Drought-Tolerant Shrubs to Boost Your Garden's Resilience
Planting drought-tolerant shrubs is a good way to ensure that your landscape looks lush and full, even in times of limited rainfall. The options on this list include beautiful evergreens, blooming shrubs, plants with showy berries, and shrubs that turn gorgeous colors in the fall. Several are natives that are adapted to growing conditions across much of the country.
While these shrubs are drought tolerant once established, they will need regular watering for the first three months after planting to help them grow a robust root system.
Bayberry
An easy-to-grow North American native, bayberry (Myrica pensylvanica) has fragrant, glossy, gray-green leaves that remain evergreen in the warmer parts of its range. Plant several of these tough shrubs together to create a screen or informal hedge. Male and female plants are needed to produce the grayish blue berries, which attract birds.
Growing Conditions: Full sun to part shade and well-drained soil
Size: 5 to 8 feet tall and wide
Zones: 3-7
Bluebeard
A mounding, deciduous shrub, bluebeard (Caryopteris spp.) is one of just a handful of shrubs that bloom in late summer and fall. It is covered with light blue flowers that make it look like it’s enveloped in a blue mist. The flowers attract many pollinators, especially butterflies.
Growing Conditions: Full sun and loose, well-drained soil
Size: 2 to 3 feet tall and wide
Zones: 5-8
Creeping Juniper
An evergreen native to North America, creeping juniper (Juniperus horizontalis) has long, trailing branches covered with needle-like, blue-green foliage in summer.

Shrubby Cinquefoil
Yellow flowers open sporadically in summer on this fast-growing deciduous shrub. Shrubby cinquefoil (Potentilla fruticosa) thrives in cooler climates and grows best where heat and humidity are low. Prune it as needed in spring to maintain a pleasing mounded shape. This drought-tolerant shrub is popular with butterflies.
Growing Conditions: Full sun and average soil
Size: 2 to 4 feet tall and 3 to 5 feet wide
Zones: 3–7
Siberian Cypress
The feathery, soft evergreen foliage of this low-growing evergreen groundcover is an excellent addition to the landscape. Pair Siberian cypress (Microbiota decussata) with drought-tolerant shrubs such as Fine Line buckthorn and smoke tree for a pleasing texture contrast. Siberian cypress, unlike many shrubs, grows well in part shade.
Growing Conditions: Full sun or part shade and well-drained soil. Grows best in regions with cool summers.
Size: 1 to 2 feet tall and 3 to 12 feet wide
Zones: 3–7
Smoke Tree
While it is called a smoke tree (Cotinus coggygria), this deciduous plant also grows as a large multi-stemmed shrub. It has a loose, spreading habit and blue-green leaves that turn shades of yellow, orange, and purple in fall. Its name is inspired by its flower clusters that turn pink and cover the tree with hazy, smoke-like puffs in summer.
The sap of smoke tree is toxic to humans.
Growing Conditions: Full sun and average to poor soil with excellent drainage
Size: 10 to 15 feet tall
Zones: 5–8
Snowberry
Snowberry (Symphoricarpos albus) has tiny pink-to-white flowers in summer that give way to clusters of pure white berries in fall (a pink-fruited variety is pictured here). The berries often stay on the deciduous, spreading plant all winter because birds don’t find them appetizing. This easy-to-grow North American native shrub works well in a loose hedge and for controlling erosion on slopes.
The berries of snowberry are toxic to humans and pets when ingested.
Growing Conditions: Full sun to part shade and well-drained soil
Size: 3 to 6 feet tall and wide
Zones: 3–7
St. John’s Wort
Sunny yellow flowers cover this summer-blooming shrub for weeks. St. John’s Wort (Hypericum spp.) is deciduous, but colorful berries decorate the plant in fall and persist into winter. Plant it near an entryway or in a mixed border where it will add instant interest.
St. John’s wort is toxic to humans, dogs, cats, and horses.
Growing Conditions: Full sun to part shade and average soil
Size: 1 to 4 feet tall and wide
Zones: 3–8
Weigela
Hummingbirds love the tubular pink or red flowers of this medium-sized shrub. There are several cultivars of weigela (Weigela florida)—look for varieties with burgundy, variegated, or chartreuse foliage. Weigela blooms in early summer. And while this shrub tolerates drought well, it will flower for a longer period of time if watered through dry spells.
Growing Conditions: Full sun and well-drained soil
Size: 1 to 4 feet tall and wide
Zones: 4-9
Yaupon Holly
Evergreen yaupon holly (Ilex vomitoria) features dense branches and glossy, dark green leaves that are evergreen. Both male and female plants are needed to produce the attractive red berries. This holly tolerates a wide range of soils and can withstand both drought and flooding. Yaupon holly quickly grows into a very large shrub, but ‘Stoke’s Dwarf’ and ‘Nana’ are compact cultivars perfect for small gardens.
The berries of yaupon holly are food for wildlife but are toxic when ingested by humans and pets.
Growing Conditions: Full sun to part shade and average soil
Size: up to 10 feet tall and 8 feet wide
Zones: 7–9
Yew
If you are looking for a drought-tolerant shrub you can sculpt into a formal hedge, yew (Taxus spp.) might be a good fit. Its thin, needle-like leaves are dark green and keep their color year-round. The plants have a pleasing, loose habit when not pruned regularly.
Be careful planting yew shrubs around children and animals because most parts of the plant are toxic if ingested.
