Deer-Resistant Plants for Utah Landscapes

Why deer pressure varies by location

Deer browsing is a significant concern in Utah communities at the foothills and canyon edges — areas like Draper, Cottonwood Heights, Sandy, South Jordan, and communities along the Wasatch Front where residential development meets deer habitat. Deer pressure is less consistent in the urban core of Salt Lake City but can be substantial in neighborhoods adjacent to open space, parks, and undeveloped land.

Deer behavior also varies seasonally. Browsing pressure is typically highest in late fall and winter when natural forage is limited, and in early spring when new growth is most palatable. A plant that deer ignore in summer may be heavily browsed in February.

"Deer-resistant" is not "deer-proof"

No plant is completely immune to deer browsing. Deer-resistant plants are those that deer tend to avoid under normal conditions — typically because of strong fragrance, coarse or spiny texture, toxic compounds, or low palatability. Under high deer pressure or food scarcity, deer will browse plants they would otherwise avoid.

The most effective approach to deer management in a residential landscape is not to rely on a single strategy but to combine plant selection with other deterrents — physical barriers around vulnerable plants, motion-activated deterrents, and consistent application of repellents where needed.

Deer-resistant trees

Trees are generally less vulnerable to deer browsing than shrubs and perennials, but young trees with low branches and tender bark are at risk. The following trees are less palatable to deer and establish well in Utah conditions:

• Hackberry (Celtis occidentalis): native to the Intermountain West; deer tend to avoid it; tolerates alkaline soil and drought.
• Honeylocust (Gleditsia triacanthos var. inermis): deer generally avoid; tolerates alkaline and compacted soils.
• Bur oak (Quercus macrocarpa): deer tend to avoid mature oaks; long-lived; drought-tolerant once established.
• Colorado blue spruce (Picea pungens): deer generally avoid conifers with stiff, sharp needles.
• Rocky Mountain juniper (Juniperus scopulorum): native; deer tend to avoid junipers; very drought-tolerant.

Deer-resistant shrubs

Aromatic shrubs are among the most reliable deer-resistant plants for Utah landscapes. Strong fragrance is one of the most consistent deterrents to deer browsing.

• Big sagebrush (Artemisia tridentata): native; strongly aromatic; deer avoid it; extremely drought-tolerant.
• Rabbitbrush (Ericameria nauseosa): native; aromatic; deer avoid it; bright yellow fall flowers.
• Apache plume (Fallugia paradoxa): native; deer tend to avoid it; white flowers followed by feathery seed heads.
• Fernbush (Chamaebatiaria millefolium): native; aromatic; deer avoid it; white flowers.
• Barberry (Berberis thunbergii): thorny; deer avoid it; tolerates alkaline soil and drought.
• Potentilla (Dasiphora fruticosa): deer tend to avoid it; long bloom season; tolerates alkaline soil.
• Lilac (Syringa vulgaris): deer generally avoid mature lilacs; fragrant spring bloom.
• Mugo pine (Pinus mugo): deer tend to avoid pines with stiff needles; compact evergreen.

Deer-resistant perennials

Aromatic and toxic perennials are the most reliable deer-resistant choices. The following perform well in Utah's alkaline soil and dry conditions:

• Russian sage (Perovskia atriplicifolia): strongly aromatic; deer avoid it; extremely drought-tolerant.
• Catmint (Nepeta spp.): aromatic; deer avoid it; long bloom season.
• Yarrow (Achillea millefolium): aromatic; deer tend to avoid it; tolerates poor alkaline soil.
• Salvia (Salvia spp.): aromatic; deer generally avoid salvias; drought-tolerant.
• Penstemon (Penstemon spp.): deer tend to avoid it; native species available; attracts hummingbirds.
• Blanket flower (Gaillardia spp.): deer tend to avoid it; long bloom season; drought-tolerant.
• Ornamental grasses: deer generally avoid most ornamental grasses; blue oat grass and Karl Foerster feather reed grass are reliable choices for Utah.

Plants deer commonly browse

The following plants are frequently browsed by deer in Utah landscapes and should be used with caution in high-deer-pressure areas, or protected with physical barriers:

• Roses (Rosa spp.): highly palatable to deer; require protection in deer-pressure areas.
• Hostas: highly palatable; deer will browse them to the ground.
• Daylilies (Hemerocallis spp.): frequently browsed.
• Tulips and other spring bulbs: deer will dig and eat bulbs in some areas.
• Arborvitae (Thuja spp.): heavily browsed, especially in winter when other forage is scarce.
• Yews (Taxus spp.): frequently browsed despite being toxic to many animals.
• Fruit trees: deer browse both foliage and fruit; young trees need protection.

Design strategies for deer-pressure areas

Plant selection is the foundation of a deer-resistant landscape, but design decisions also matter. Concentrating vulnerable plants in areas close to the house — where human activity is frequent — reduces browsing pressure. Deer are more cautious near structures and activity.

Using deer-resistant plants as a perimeter layer around more vulnerable plantings creates a buffer that reduces browsing on interior plants. Aromatic shrubs like sagebrush and rabbitbrush are effective perimeter plants in Utah landscapes.

Physical barriers — wire cages around individual plants, deer fencing around planting beds — are the most reliable protection for vulnerable plants. Fencing needs to be at least 8 feet tall to reliably exclude deer; shorter fencing may deter casual browsing but will not stop determined deer.
