Perennials give a xeriscape color; shrubs give it bones. Without them, a low-water bed reads as a flat sea of small plants that vanishes in winter. The right drought-tolerant shrubs add height, screen the neighbor's trampoline and feed pollinators and birds, on a fraction of the water a hedge of arborvitae demands. These 12 are proven in the cold interior West (zones 4–8 for most), with a short list of hot-desert additions at the end.
Drought tolerance starts after establishment. CSU Extension notes that many woody plants need at least two growing seasons to establish, so water every shrub here deeply through its first two summers, then taper.

Mid-size shrubs for structure
1. Rabbitbrush (Ericameria nauseosa)
Zones 4–9 · Water Very low · Size 2–5 ft tall (older plants larger) · Bloom September to October, gold
Silver-blue foliage all season, then an explosion of gold in fall when little else blooms. Rabbitbrush is native across the West, a major late-season nectar source, and needs no water once established.
Care tip: Cut it back by a third to a half in early spring to keep it dense.
2. Apache plume (Fallugia paradoxa)
Zones 4–8 · Water Very low · Size 4–6 ft × 4–6 ft · Bloom Late spring to fall, white, with pink feathery seed plumes
White rose-like flowers and pink, feathery seed plumes at the same time, for months. Apache plume is a Plant Select winner, semi-evergreen, and tough enough for a hell strip.
Care tip: Thin a few of the oldest stems at the base every few years rather than shearing.
3. Fernbush (Chamaebatiaria millefolium)
Zones 4–8 (Plant Select: 4b–8) · Water Very low · Size 5–6 ft × 5–6 ft · Bloom July, white spikes
Fragrant, ferny foliage and white summer flower spikes covered in bees. Fernbush is tidy and rounded, and one of the best pollinator shrubs for cold-winter xeriscapes. Plant Select rates it zones 4b–8.
Care tip: Deadhead the brown flower spikes in fall or early spring for a cleaner look.
4. Blue mist spirea (Caryopteris × clandonensis)
Zones 5–9 · Water Low · Size 2–3 ft × 2–3 ft · Bloom Late summer to early fall, blue
A mound of true-blue flowers when the garden needs it most, busy with bumblebees.
Care tip: Cut it nearly to the ground each spring; it blooms on new growth.
5. Big sagebrush (Artemisia tridentata)
Zones 4–9 · Water Very low · Size 3–6 ft × 3–6 ft · Feature Evergreen silver foliage, fragrant
The scent of the West after rain. Big sagebrush gives evergreen silver structure and is a keystone native of the Great Basin and high desert.
Care tip: Once established, don't irrigate it at all; water is the one thing that kills it.
6. Three-leaf sumac (Rhus trilobata)
Zones 4–8 · Water Very low · Size 4–6 ft × 5–8 ft · Feature Orange-red fall color, tart red berries
Glossy summer leaves, strong orange-red fall color, and berries birds use. Three-leaf sumac handles slopes, clay and wind. The compact 'Autumn Amber' works as a tall groundcover.
Care tip: It suckers slowly into a thicket; use that on slopes and give it room elsewhere.
7. Western sand cherry (Prunus besseyi)
Zones 3–8 · Water Low · Size 3–6 ft × 4–6 ft · Bloom Spring, white; black cherries in summer
A Great Plains native with white spring flowers, edible (if tart) cherries and good fall color. 'Pawnee Buttes' is a low Plant Select form used as a groundcover.
Care tip: Give it full sun and good air circulation to limit leaf spot.
8. Panchito manzanita (Arctostaphylos × coloradensis 'Panchito')
Zones 4–8 · Water Very low · Size 10–15 in × 2–3 ft · Bloom Early spring, pale pink
A low broadleaf evergreen with mahogany stems: a shrub that acts like a groundcover. Panchito manzanita gives the front of a shrub border year-round green.
Care tip: Plant it in spring and mulch with gravel or fine bark, not deep wood chips.
Taller shrubs for privacy
9. Mountain mahogany (Cercocarpus montanus)
Zones 4–8 (MBG: 5–10) · Water Very low · Size 6–10 ft × 5–8 ft · Feature Silvery, feathery seed tails in late summer
A Front Range foothills native with small, toothed leaves and curly seed tails that glow when backlit. The Missouri Botanical Garden rates it zones 5–10; native stands grow colder, and we rate it to zone 4 in dry, well-drained sites.
Care tip: It's browsed by deer; protect young plants with cages for the first few years.
10. Curl-leaf mountain mahogany (Cercocarpus ledifolius)
Zones 3–8 · Water Very low · Size 8–15 ft × 6–10 ft · Feature Evergreen, feathery seed tails
A broadleaf evergreen for cold, dry climates, which is rare and valuable. Slow, dense and architectural, it can be grown as a large shrub or small tree.
Care tip: Plant it in lean, well-drained soil and be patient; it grows slowly for the first few years.
11. New Mexico privet, desert olive (Forestiera pubescens, syn. F. neomexicana)
Zones 4–9 · Water Very low · Size 8–15 ft × 10–12 ft · Feature Yellow fall color, early nectar flowers, bird berries
The workhorse xeric screen: fast-growing, fine-textured, with yellow fall color. It can be sheared as a hedge or left natural.
Care tip: For privacy, plant a staggered row 4 to 6 feet apart; it fills in within three seasons.
12. Silver buffaloberry (Shepherdia argentea)
Zones 3–7 · Water Low to moderate · Size 8–12 ft · Feature Silver leaves, red berries, thorny branches
Silver foliage, red berries for birds, and thorns that make it a real barrier. It's hardy into the coldest zones. The Missouri Botanical Garden lists medium water, so give it occasional deep summer water rather than none.
Care tip: Plant both male and female plants if you want berries.
Two more for tough spots: fourwing saltbush (Atriplex canescens), a gray, semi-evergreen native that takes alkaline soil, road salt and reflected heat, and shrubby cinquefoil (Potentilla fruticosa, zones 2–7), which blooms all summer but needs more water than the rest of this list.
Warm-climate additions (zones 7 and up)
In the low-elevation Southwest and Texas, add Texas sage or cenizo (Leucophyllum frutescens, zones 8–11; the Missouri Botanical Garden rates it zones 8–10), with silver foliage and purple flushes after summer rain, and autumn sage (Salvia greggii, zones 6–9) for long red, pink or coral bloom. See the Phoenix and St. George guides for regional palettes.
Designing with xeric shrubs
- Place shrubs first, perennials after. Structure sets the frame and color fills it. The full sequence is in 10 steps to xeriscaping.
- Mix evergreen and deciduous roughly one to two, so winter isn't empty and summer isn't heavy.
- For privacy, plant staggered double rows instead of a single line. They screen faster, and one lost plant doesn't leave a gap.
- Don't shear natives into balls. Most of these look and bloom best in their natural form with one light pruning a year.
- Keep them out of the lawn zone. CSU recommends planting reduced-water shrubs separate from irrigated lawns, or they'll get far more water than they want.
Planting and establishment
Dig the hole two to three times as wide as the pot and no deeper, skip the fertilizer, mulch, and water deeply once or twice a week through the first summer, then less often in the second. On clay, test drainage first: CSU suggests digging an 18-inch hole, filling it with water and checking that it drains within 30 minutes; if not, plant on a berm. Most losses come from too much water, not too little: sagebrush, rabbitbrush and apache plume rot in irrigated beds.
From our installs
On the Front Range, shrubs are where clay soil bites hardest. We plant slightly high, backfill with the native soil, and water new shrubs deeply once or twice a week for the first summer and every week or two the second summer, then taper. The common failures we see are sagebrush and apache plume planted on a lawn's sprinkler zone, and privacy screens planted in a single straight row that never fills in. Hail strips leaves some summers, but deciduous natives leaf out again quickly. Deer browse mountain mahogany and sand cherry, so we cage young plants in the foothills.

Frequently asked questions
What is the best drought-tolerant shrub for privacy?
New Mexico privet grows fastest into a screen. Curl-leaf mountain mahogany is the best evergreen option for cold, dry climates, though it's slow.
Which drought-tolerant shrubs are evergreen?
Big sagebrush, curl-leaf mountain mahogany and Panchito manzanita. Apache plume is semi-evergreen.
How long until drought-tolerant shrubs are established?
Most need two growing seasons of regular deep watering before you can cut back to occasional summer soaks.
What shrubs attract pollinators in a xeriscape?
Fernbush, apache plume, blue mist spirea and rabbitbrush are all heavily used by bees and butterflies.
For layered plantings, pair these with drought-tolerant perennials and ornamental grasses. For backyard screening layouts, see backyard xeriscape ideas, and for trees to go with them, see low-water trees.
