Central Utah Keystone Native Plants

A reference guide for the Intermountain West cottage gardener

Data sourced from NWF / Dr. Doug Tallamy research  ·  Ecoregion 10: North American Deserts  ·  Ecoregion 6: Northwestern Forested Mountains
Central Utah sits at the intersection of both — plants marked ★ appear on both ecoregion lists

Not all native plants carry equal ecological weight. Research by entomologist Dr. Doug Tallamy found that just 14% of native plant genera support 90% of caterpillar species — and caterpillars are the essential food source for nearly every nesting songbird. The plants below are the keystone species confirmed for Central Utah and the broader Intermountain West. Species counts reflect Tallamy's University of Delaware research and pollinator data from conservationist Jarrod Fowler. Wildlife lists show primary beneficiaries; actual totals are far higher.

Trees

Gambel Oak ★
Quercus gambelii
208 caterpillar spp.

The reigning keystone tree of Central Utah. Grows on dry foothills and canyon walls from 4,000–8,000 feet — exactly the elevations where most Wasatch Front and central Utah gardeners live. Functions as a large shrub or small tree, spreading by underground runners into thickets that provide exceptional wildlife cover. Acorns are a critical autumn food source. Turns gold, orange, and brick-red in fall.

Garden note: Drought-tolerant once established. Spreads by root sprouts — give it room or plant at a property edge. One of the single highest-impact plants you can add to a Utah landscape. Hardiness zones 3–9.

Chokecherry ★
Prunus virginiana
200–206 caterpillar spp.

The second-highest caterpillar host in the region and arguably the most versatile — functions as a large shrub or small tree, works in moist canyon soils and drier slopes alike. Clusters of fragrant white spring flowers precede dark purple-black berries that birds descend on in late summer. One of the most wildlife-productive shrubs or small trees available to Utah gardeners.

Garden note: Suckers freely — excellent for naturalized areas or habitat edges. Spring bloom is beautiful; fall berry clusters ornamental and wildlife-rich. One of the easiest high-value natives to establish in Utah gardens.

Quaking Aspen & Cottonwood ★
Populus tremuloides / P. fremontii
184–197 caterpillar spp.

Aspens are the iconic tree of Utah’s mountain communities; Fremont cottonwood anchors the riparian corridors of lower elevations. Both are powerhouse caterpillar hosts. Aspens grow in clonal colonies connected underground. Their trembling leaves and bone-white bark are among the most distinctive sights in the Intermountain West.

Garden note: Aspen suits mountain gardens above 6,000 ft; Fremont cottonwood works at lower elevations near water. Both spread aggressively by root sprouts — plan for space.

Ponderosa Pine ★
Pinus ponderosa
163–165 caterpillar spp.

The signature pine of Utah’s middle-elevation forests (5,500–8,000 ft). Vanilla-scented bark on mature trees. Provides year-round structure, seeds for birds throughout winter, and nesting habitat. Slow-growing but exceptionally long-lived — a multigenerational garden plant in the truest sense.

Top wildlife supported (of 163+ species)

Garden note: Needs well-drained soil and full sun. Not suitable for valley bottoms or heavy clay. Best at elevations matching its natural range (5,500 ft+).

Water Birch ★
Betula occidentalis
153–177 caterpillar spp.

Utah’s native birch, found along stream banks and canyon bottoms throughout the state. Multi-stemmed with attractive dark reddish-brown bark and graceful catkins. Far better suited to Utah’s soils and water cycles than European or paper birch, which struggle here. An excellent choice for any garden spot with seasonal moisture or a low area.

Garden note: Prefers moist, well-drained soil. Thrives along irrigation channels, drainage areas, or supplemented beds. Far more reliable in Utah than non-native birch cultivars.

Rocky Mountain Maple
Acer glabrum
102–107 caterpillar spp.

Utah’s native maple — a large multi-stemmed shrub or small tree that turns brilliant red, orange, and gold in fall. Common in canyon bottoms and mountain foothills throughout the state. Far better adapted to Utah’s soils and climate than ornamental maple cultivars. The winged seeds (samaras) are a valuable late-season food source for birds and small mammals.

Top wildlife supported (of 102+ species)

Shrubs

Coyote Willow ★
Salix exigua (and other native Salix spp.)
240–256 caterpillar spp.19–26 specialist bee spp.

The single most ecologically productive plant genus in the Intermountain West — native willows support more caterpillar species than any other plant in the region. Coyote willow is the most widely available Utah-native species: a slender, multi-stemmed shrub found along streams and washes throughout the state. Spreads by root sprouts to stabilize banks and create dense habitat thickets.

Garden note: Best sited along drainage areas, irrigation channels, or any low spot with seasonal moisture. Spreads readily — excellent as a habitat planting rather than a formal specimen. Invaluable for erosion control.

Rubber Rabbitbrush ★
Ericameria nauseosa
20 caterpillar spp.73–89 specialist bee spp.

The most important shrub for native bees in Central Utah — supporting more pollen specialist bee species than almost any other plant on both ecoregion lists. Explodes into bright yellow bloom in late summer and fall, exactly when most other plants are winding down. Extremely drought-tolerant; thrives in alkaline and poor soils. The backbone of any pollinator-focused garden on the dry Wasatch Front.

Garden note: One of the very best plants for dry, alkaline soils common throughout the Salt Lake Valley. Nearly indestructible once established. Spectacular when almost nothing else blooms in fall.

Yellow Rabbitbrush ★
Chrysothamnus viscidiflorus
24 caterpillar spp.78–87 specialist bee spp.

Smaller and more refined than rubber rabbitbrush, this species works well in garden settings while still delivering extraordinary value for native bees. Lower, more compact habit with narrow grayish foliage. Bright yellow flowers in late summer. Thrives in the gravelly, well-drained soils of Utah’s valleys and foothills.

Garden note: A refined, garden-friendly alternative to larger rabbitbrush. Excellent in xeriscapes, rock gardens, or dry borders. Plant in drifts for best visual and ecological effect.

Serviceberry (Saskatoon)
Amelanchier alnifolia
60+ caterpillar spp.

One of the most ornamentally beautiful native shrubs in Utah — white flowers in early spring, blue-purple berries in summer, excellent fall color. A four-season plant with exceptional wildlife value. The berries are among the most nutritious available to wildlife and disappear within days of ripening. One of the first shrubs to bloom in spring, providing critical early nectar to emerging pollinators.

Garden note: The most garden-friendly keystone shrub for Central Utah. Adaptable to a range of soils; moderate water needs. Works beautifully in a cottage garden setting alongside roses and perennials.

Dwarf Bilberry / Thinleaf Huckleberry ★
Vaccinium caespitosum / V. membranaceum
111–116 caterpillar spp.

Utah’s native Vaccinium species — low-growing, mat-forming shrubs found in mountain forests and subalpine zones. The berries are intensely flavored and a critical food source for bears, grouse, and birds before winter. Best suited to mountain-area gardens at higher elevations with acidic, moist soil.

Flowering Perennials

Native Sunflower ★
Helianthus petiolaris / H. nuttallii
39–52 caterpillar spp.81–84 specialist bee spp.

Native sunflowers are powerhouses for both caterpillars and native bees — supporting over 80 specialist bee species alone. Plains sunflower (H. petiolaris) is the dry-adapted species suited to Utah’s sandy and gravelly soils. Nuttall’s sunflower (H. nuttallii) prefers moist areas near streams and ditches. Both are undemanding, cheerful, and ecologically extraordinary.

Garden note: Self-seeds freely — let a patch naturalize and it will maintain itself. Goldfinches work the seedheads from September through February. One of the most ecologically productive additions to any Central Utah garden.

Western Goldenrod ★
Solidago lepida / S. multiradiata
51–52 caterpillar spp.46–48 specialist bee spp.

The Utah-native counterpart to the eastern goldenrods — equally valuable, and completely unfairly blamed for hay fever (ragweed is the culprit). Blooms late summer into fall when almost nothing else is open, making it a lifeline for migrating monarchs, bees fueling up for winter, and late-season caterpillars. Rocky Mountain goldenrod (S. multiradiata) handles higher elevations; western goldenrod (S. lepida) works across a broader range.

Garden note: Spreads by rhizomes — plant where it can naturalize. Excellent back-of-border plant with genuine late-season color. Goldenrod pollen is too heavy to be airborne; it does not cause hay fever.

Broom Snakeweed ★
Gutierrezia sarothrae
7 caterpillar spp.72–89 specialist bee spp.

Unassuming and often overlooked, but one of the most important plants for native bees in the entire Intermountain West. A low, woody-based perennial covered in tiny yellow flowers in late summer. Extremely drought-tolerant; native to dry plains and foothills throughout central Utah. The bees know what gardeners often don’t — this plant is extraordinary.

Garden note: Perfect for dry, gravelly, or alkaline soils where little else thrives. Best in habitat-style plantings or at the naturalistic edges of a more formal garden. Invaluable for supporting native bees.

Western Aster ★
Symphyotrichum ascendens / S. eatonii
~108 caterpillar spp. (genus)29–31 specialist bee spp.

Utah’s native asters — western aster and Eaton’s aster — are the autumn workhorse of the cottage garden. Purple and lavender daisy-like flowers from late August into October, bridging the critical gap when summer bloomers have faded. Essential for migrating monarch butterflies and late-season pollinators. The genus Symphyotrichum as a whole supports approximately 108 caterpillar species.

Garden note: Seek out Utah-native Symphyotrichum species rather than eastern cultivars. Western aster (S. ascendens) is the most widely available and best adapted to Utah’s dry, alkaline soils. Stunning in mass plantings.

Hairy False Goldenaster ★
Heterotheca villosa
6–8 caterpillar spp.56–65 specialist bee spp.

A low-growing, sprawling perennial with silvery-hairy foliage and bright golden-yellow daisy flowers throughout summer and into fall. Native to dry, rocky slopes and disturbed ground throughout Utah. Largely unknown to most gardeners but a superstar for native bees. An excellent groundcover-height plant for sunny, dry areas.

Garden note: Thrives in poor, dry, rocky soils in full sun — perfect for slopes, rock gardens, or areas where conventional plants struggle. A low-care, high-value plant that rewards benign neglect.

Curlycup Gumweed ★
Grindelia squarrosa
8 caterpillar spp.71–75 specialist bee spp.

Bright yellow daisy flowers with distinctive sticky, curled bracts — found on roadsides and disturbed ground throughout Utah. Thrives in poor, alkaline soils. The resinous buds have a long history of traditional medicinal use. Exceptional for native bees, supporting over 70 specialist species. Blooms midsummer into fall, overlapping with goldenrod and aster to create a continuous late-season nectar corridor.

Scarlet Globemallow
Sphaeralcea coccinea / S. grossulariifolia
27 specialist bee spp.

The brilliant orange-red flowers of native globemallow are one of the most cheerful sights in dry Utah landscapes from spring through midsummer. Low-growing, drought-adapted, and native to a wide range of soils across central Utah. Certain Diadasia bees can only collect pollen from Sphaeralcea and closely related genera — an ecological specialist’s plant with broad ornamental appeal.
