The Best Shrubs for Western Montana Yards, by the Job They Do

What makes a shrub right for western Montana?

Hardiness, drought tolerance once established, and tolerance of the alkaline, often gravelly soils of the valley floors. MSU's deer damage MontGuide gives a rule of thumb of choosing perennial plants adapted to Zones 4 and 5 for western Montana gardens. The 2025 MSU MontGuide Native Plants for Montana's Home Gardens lists each shrub with a hardiness zone range, and the ranges for the natives below all include zones 4 and 5, with most reaching colder than that, which leaves a margin for cold pockets and exposed benches. Our guide to hardiness zones for Missoula and the Bitterroot explains what the zones mean for a given lot.

Mature size is the other test. Most shrub problems we are asked to fix are shrubs planted too close to a house, walk or window. The sizes below come from the NRCS publication Montana Native Plants for Pollinator-Friendly Plantings unless noted. This guide is part of our Montana Landscaping, Lawn & Irrigation Guide.

Which native shrubs are the most dependable?

Serviceberry (Amelanchier alnifolia): MSU lists it for zones 2 to 7. NRCS describes it as 2 to 16 feet tall, suckering to a 4 to 10 foot spread, low water use, full sun to very light shade, blooming May to June. MSU's water management MontGuide notes that serviceberry thrives where it is hot and dry.

Golden currant (Ribes aureum): zones 3 to 8 in MSU's list. NRCS gives 3 to 6 feet tall and wide, tolerant of sandy to clay soils, low water use, blooming April to May. Its flowers are among the earliest food for bees in the NRCS bloom chart. Chokecherry (Prunus virginiana): zones 2 to 7; 10 to 15 feet, suckering, low water use, April to May bloom. Best at the edge of a property rather than beside a patio.

Woods rose (Rosa woodsii): zones 3 to 8; 4 to 5 feet tall, suckering to a 4 to 10 foot spread, low water use, July bloom. That spread makes it better on banks and in hedgerows than in a tidy bed. Common snowberry (Symphoricarpos albus): zones 3 to 7; to about 3 feet tall and wide, loamy to clay soils, low water use, blooming June to August. Shrubby cinquefoil (Dasiphora fruticosa, sold as potentilla): zones 3 to 7 in MSU's list, and on MSU's fire-resistant list as well.

Which shrubs work for screens and hedges?

For a tall, informal screen, the suckering natives do the job without much help: chokecherry, silver buffaloberry (3 to 20 feet and thicket forming, per NRCS) and American plum (6 to 10 feet). They need room, and they spread. For a more contained screen, lilacs are the traditional choice. MSU's lilac MontGuide says the common lilac is very hardy, quite drought tolerant and commonly used in shelterbelts and hedges, and that Montana lilacs typically stay under 10 feet.

MSU singles out Chinese lilac as one of the best lilacs for taller hedges, 10 to 12 feet tall, with fewer suckers than common lilac, though it is very susceptible to powdery mildew. Meyer lilac stays 4 to 5 feet and suits low hedges. MSU also warns that early-blooming hyacinthiflora lilacs are not recommended where May frosts are common, and that lilacs should not go in frost pockets or against warm, light-colored walls that force early buds.

Which shrubs handle wet spots or partial shade?

Redosier dogwood (Cornus sericea) is the usual choice for moist ground: zones 3 to 8 in MSU's list, 4 to 7 feet tall with a 4 to 6 foot spread, loam to clay soils, medium water use, full sun to partial shade per NRCS. Blue elderberry grows 6 to 15 feet with moderate water, partial shade to full sun. MSU's water management MontGuide notes that golden currant also flourishes in low-lying areas where water collects.

Shade is harder, because most of the dependable natives here are full-sun plants in the NRCS descriptions. Skunkbush sumac (full sun to partial shade) and redosier dogwood tolerate some shade; for deeper shade, ask about the specific site, and look at the MSU list's ninebarks (zones 2 to 8) and creeping barberry (Mahonia repens, zones 4 to 8) with a nursery that knows the local conditions. If a planting area holds water for days after rain, fix the drainage first; see standing water in the lawn and rain gardens.

Which shrubs take hot, dry, unirrigated ground?

The sagebrush steppe shrubs. MSU's native list includes big sagebrush, silver sagebrush, rubber rabbitbrush and yellow rabbitbrush, four-wing saltbush, winterfat, bitterbrush, curl-leaf mountain mahogany and skunkbush sumac. NRCS describes rabbitbrush as 2 to 4 feet tall and wide, low water use, blooming August to October, and skunkbush sumac as 2 to 10 feet, forming thickets, low water use and flowering in April before its leaves open.

These are the backbone of a xeriscape or an unirrigated acreage edge. They still need watering to establish: the NRCS guide recommends watering native shrubs weekly or every two weeks for the first two to three years. Several of these, sagebrush included, are aromatic, which matters near a house in fire country (see below).

Which shrubs are best for pollinators and birds?

Most of the native flowering shrubs above. MSU's 2025 native plant list flags pollinator value and food for birds, and NRCS's bloom chart shows the shrubs carrying the early season: sumac in April, currant, chokecherry, plum and dogwood April to May, serviceberry and buffaloberry May to June, then snowberry, elderberry and Woods rose into midsummer and rabbitbrush into October. Our pollinator garden guide builds a full bloom sequence around them.

MSU's pollinator article also recommends shrubs with hollow or pithy stems, such as elderberry and raspberry, cut at varying heights for stem-nesting bees.

Which shrubs are safer near a house in fire country?

Most deciduous shrubs. MSU's fire-resistant plants MontGuide says fire-resistant plants have supple, moist leaves and watery sap, while flammable plants generally have aromatic leaves with gummy or resinous sap. It names junipers as a good example of a highly flammable plant that should not be used as a foundation plant in the wildland-urban interface, and says most deciduous shrubs are fire-resistant and should be considered for foundation plantings.

Its list of fire-resistant shrubs includes buffaloberry, chokecherry and other Prunus, shrubby cinquefoil, currants and gooseberries, redosier dogwood, honeysuckle, common lilac, mountain mahogany, mock orange, raspberry, most members of the rose family and skunkbush sumac. No plant is fireproof: MSU says any plant will burn if dry enough. See junipers and other high-risk shrubs and fire-resistant plants for spacing near buildings.

Will deer eat these shrubs?

Some, and none are guaranteed. MSU's deer MontGuide says deer-resistant does not mean deer-proof and that no plant is safe from a hungry deer. It adds that young and newly transplanted plants are browsed more heavily than established ones, and that well-fertilized trees and shrubs are more attractive to deer. Protect new shrubs with cages for the first few winters in deer country.

Our deer-resistant plants list gives MSU's ratings, and deer browse in winter covers protection.

Which shrubs should you not plant in Montana?

Anything on the state noxious weed list, and the regulated species. On the Montana Noxious Weed List (effective June 21, 2019, as reproduced in an October 2025 legislative committee packet), Scotch broom is Priority 1B, common buckthorn is Priority 2A, and saltcedar (tamarisk) is Priority 2B. Russian olive is a Priority 3 regulated plant: the list says regulated plants may not be intentionally spread or sold other than as a contaminant in agricultural products.

Lists change, so confirm with your county weed district before planting anything unfamiliar from out of state. Our guide to Ravalli County noxious weeds explains the landowner duty.

When should shrubs be planted in western Montana?

Spring or early fall. MSU's 2025 native plant MontGuide says nursery-grown plants transplant well in spring before temperatures get too hot and soils dry, and in fall after the summer heat while the soil is still warm, and that bare-root trees and shrubs should be planted while dormant in early spring. Water until established, which MSU says can take a growing season or longer for shrubs.

Our guides to fall planting and protecting shrubs over winter cover the first year.

Can HJ plant shrubs as part of a landscape?

Yes. Shrub planting is part of our landscaping design service, from a single foundation bed to screens along a property line, with drip irrigation to establish them. For trees, see our guide to trees for western Montana.
