The Western Shortgrass Prairie is the second-largest grassland ecoregion in North America, spanning the High Plains from Texas and New Mexico north to Nebraska and Wyoming. Its landscape is dominated by sod-forming perennial grasses such as blue grama and buffalograss, with mixed-prairie stands of needle-and-thread grass, western wheatgrass, and June grass. The climate is semi-arid, ranging from subhumid warm-temperate in the south to cold-temperate in the north, with annual precipitation of roughly 250-630 mm and recurrent late-summer droughts. Though under 1% is formally protected, about 56% of the habitat outside protected areas—almost all of it private land—remains essentially intact.

Use this as the broad planting pattern for the region: Temperate prairies, steppes, and pampas of grasses and forbs with few trees, under continental climates of hot summers and cold winters. Their deep, fertile soils have made them among the most extensively converted biomes for agriculture. For garden decisions, pair that context with the plant list below, then narrow by your site's light, water, soil, and mature-size constraints.

This boundary is a modern ecological footprint for Western shortgrass prairie, not a permanent line on the planet. It is useful for today's plant and wildlife context because it follows recurring vegetation, climate, landform, and disturbance patterns.
The region sits in the Nearctic realm and is classed as temperate grasslands, savannas & shrublands. Elevation, moisture, fire, soils, coasts, and human land use can all make the real landscape more varied than a single map color suggests.

Yucca filamentosa
Adam's needle
A virtually stemless, broadleaf-evergreen native of central and eastern North America: a basal rosette of rigid, sword-shaped, spine-tipped leaves up to 30 inches long, fringed along the margins with the curly white threads that give the species its name. In early summer a flowering stalk shoots from the center to 5-8 feet, carrying nodding, bell-shaped, creamy-white flowers. Tough enough for poor sandy soil, heat, drought, and salt spray, it earns its keep as architectural structure in dry and seaside gardens.

African marigold
A tall, bold warm-season annual from Mexico and Guatemala (the "African" name is a misnomer of its European garden history) grown for large, fully double, pompon-like flowerheads in saturated yellow, gold, and orange over strongly aromatic, finely divided foliage. Plants reach 12-48 inches and bloom from early summer to frost in full sun. The petals are edible and used as a culinary garnish and natural dye, and the flowers are the iconic "flor de muerto" of Mexican Day of the Dead. Despite the wide listed zone range it is frost-tender and grown for a single warm season.

Allegheny spurge
A native Southeastern North American semi-evergreen woodland groundcover (Pachysandra procumbens), prized for its blue-green to bronze mottled leaves and fragrant white-to-pinkish bottlebrush flower spikes that open at ground level in late winter to early spring. Unlike the widely planted invasive Asian Pachysandra terminalis, this native spreads slowly by rhizomes into well-behaved clumping colonies, making it a low, restrained groundcover for shaded native plantings.

Thuja occidentalis
American arborvitae
A dense, conical-to-narrow-pyramidal evergreen tree native to eastern and central North America, prized as a screening and foundation conifer. Flat, fan-like sprays of scale-like, aromatic yellow-green foliage clothe the tree from the ground up, and red-brown bark exfoliates on mature trunks. Wild trees can reach 40-60 feet but cultivated plants typically stay near 20-30 feet; small urn-shaped cones and dense evergreen cover make it valuable food and shelter for birds.

American basswood
A medium-to-large native shade tree of central and eastern North America, reaching 50-80 feet with an ovate-rounded crown and large, asymmetric heart-shaped leaves. In June it carries pale-yellow, intensely fragrant flowers on pendulous cymes — each cluster hung from a distinctive strap-like leafy bract — that ripen into pea-sized nutlets. The fragrant June bloom is a premier nectar source: Missouri Botanical Garden lists it as attracting bees and butterflies, and the Lady Bird Johnson Wildflower Center flags it as having special value to both native and honey bees.

Castanea dentata
American chestnut
Once the dominant canopy hardwood of the eastern United States forest — an estimated four billion trees, prized for fast growth, rot-resistant timber, and an enormous annual crop of sweet edible nuts that fed people, livestock, and wildlife alike. In the early 1900s an introduced Asian fungus, chestnut blight (Cryphonectria parasitica), swept through and functionally destroyed it: by the 1950s the species was effectively extinct as a mature forest tree. Surviving root systems still send up sprouts from old stumps, but the blight almost always girdles and kills them before they can grow large enough to flower and reproduce. The honest reality for a gardener is that you cannot reliably grow a mature wild-type American chestnut today. The realistic paths are blight-resistant backcross hybrids from The American Chestnut Foundation or transgenic blight-tolerant lines still being deployed — not a pure wild seedling, which the blight will almost certainly kill.

Sambucus canadensis
American elderberry
A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.

Teucrium canadense
American germander
American germander, also called wood sage, is a widespread North American native perennial in the mint family that runs steadily underground on creeping rhizomes. From early to midsummer it sends up erect, softly hairy stems topped with one-sided spikes of pale pink-to-lavender flowers, each with the distinctive deeply lobed lower lip that gives the germanders their look and makes a generous landing platform for bees. It is a plant of moist open ground - wet meadows, streambanks, ditches, and the edges of thickets - across most of the contiguous United States into southern Canada, which tells you exactly what it wants: sun and a soil that does not dry out. The honest caveat is its vigor: those same rhizomes that fill a bank or a rain garden so readily will also colonize a tidy perennial border and crowd politer neighbors. Site it where it can run, or give it a root barrier, and it rewards you with a long, dependable bee-friendly bloom rather than a maintenance fight.

A rounded, multi-stemmed deciduous shrub native across eastern and central North America, grown for its edible nuts and its season-opening catkins. Showy 2-3 inch yellowish-brown male catkins dangle from bare branches in early spring before the ovate, double-toothed leaves emerge; small egg-shaped edible nuts ripen inside leafy husks by mid- to late summer. Easygoing in average soil and tolerant of clay and black walnut, it suckers into thickets that screen and shelter wildlife.

American holly
The only native U.S. holly with both spiny green leaves and bright red berries — an upright, pyramidal, broadleaf evergreen tree that slowly matures to 15-30 feet in cultivation (to 50 feet in the wild). Thick, leathery, deep green leaves bear spiny marginal teeth, and pollinated female trees carry showy red-to-orange drupes that ripen in fall and persist through winter as bird food. This is the classic "Christmas holly" of wreaths and decorations.

Not native to North America (the genus Malus spans Europe, Asia, and North America, but the cultivated apple is an Old World hybrid lineage). Almost all varieties are self-incompatible: a second, different apple cultivar blooming at the same time must be nearby for fruit to set, and trees are grown on dwarf, semi-dwarf, or standard rootstocks that decide final size.

A fast cool-season annual of the mustard family grown for its peppery, mustard-like salad greens — irregular, pinnately-lobed basal leaves in a low rosette, each with 4 to 10 small lateral lobes and a large terminal lobe (Missouri Botanical Garden). First cultivated by the ancient Greeks and Romans and still widely grown across Europe, it is best grown in the cooler spring and fall months rather than summer heat; leaves are harvested young and tender before they turn strong and bitter. Pale-yellow four-petalled flowers with dark brown or purple veins appear in corymbs if plants are left to bloom.

A small, dense, rounded evergreen citrus tree or shrub (8-15 feet) grown for its tiny oval-to-round orange fruits that are eaten whole, skin and all — the sweet, fragrant rind plays against the tart inner flesh, which is the whole point of the fruit. Among the cold-hardiest of the citrus relatives, it shrugs off brief cold better than most citrus (roughly to USDA zone 8b), yet it is still frost-tender and is widely grown in containers and greenhouses wherever winters turn cold. Native to southern China, not North America. Note the accepted botanical name is now Citrus japonica; Fortunella japonica is the widely-used synonym.

Eucalyptus globulus
Tasmanian blue gum
Tasmanian blue gum is a towering, very fast-growing evergreen tree from southeastern Australia (Tasmania and coastal Victoria) — one of the most widely planted eucalypts in the world, and one of the most widely regretted outside its native range. It reaches 90-150 feet or more, with a tall straight trunk, peeling ribbons of bark, and aromatic blue-green to gray-green foliage that carries the classic 'eucalyptus' scent. Honesty first, because it is load-bearing here: in California and other Mediterranean-climate regions this is an INVASIVE tree. It self-seeds aggressively, displaces native vegetation, and is allelopathic — its leaf litter and oils suppress the plants beneath it. Worse, it is a serious FIRE HAZARD: the oil-rich leaves, the long shedding bark ribbons, and the deep litter of dropped leaves and bark burn explosively, which is why these trees are nicknamed 'gasoline trees' and have fueled some of the most dangerous wildland fires. We strongly discourage planting Eucalyptus globulus near homes or in fire-prone, wildland-adjacent areas; plant a regionally-appropriate, fire-smart native tree instead. The aromatic foliage is the source of commercial eucalyptus oil, but that oil is TOXIC if ingested in any quantity and the foliage is not food — this is not an edible plant. It is also simply enormous and fast: not a tree for a small property.

California Central Valley grasslands
The California Central Valley grasslands fill the long lowland between the Sierra Nevada to the east and the Coast Ranges to the west, spanning the Sacramento Valley in the north and the San Joaquin Valley in the south. The climate is Mediterranean, with most rain falling in winter and conditions growing drier from north to south and on the western, rain-shadowed side. Historically a mosaic of perennial bunchgrass prairie, oak savanna, vernal pools, and riparian woodland, the region is now largely converted to farmland and dominated by introduced annual grasses. It is one of North America's most altered grasslands: less than 1% of native grassland remains and only about 4% is protected.

Central US forest-grasslands transition
The Central US forest-grasslands transition is an ecotone stretching across the central Midwest—including Illinois, Indiana, Wisconsin, Missouri, Iowa, and Kentucky—where the eastern deciduous forests of the United States give way to the tallgrass prairies of the eastern Great Plains. Its presettlement landscape was a mosaic of oak savanna, bluestem prairie, and oak-hickory and maple-basswood forest, with glacial moraines, dunes, fens, and marshes common in the Chicago Lake Plain along Lake Michigan. The climate ranges from humid warm continental to humid cold temperate. Now encompassing major metropolitan areas including Chicago and Milwaukee and reaching south toward St. Louis, the region has lost over 95% of its presettlement vegetation, with only about 3% protected.

Central-Southern US mixed grasslands
The Central-Southern US Mixed Grasslands run north to south from central Nebraska through Kansas and Oklahoma into north-central Texas, a vast prairie marking the ecological transition from tallgrass to shortgrass plains. Its flat-to-rolling, wind-deposited terrain (about 400-1,220 m elevation) carries native mixed-grass prairie of tallgrasses such as big bluestem and Indiangrass alongside shorter grasses, and OneEarth notes it holds the greatest floristic complexity of all North American grasslands. The climate is subhumid warm continental to warm temperate, with annual precipitation ranging from roughly 300 to 812 mm. Each spring more than 500,000 sandhill cranes (about 80% of the world's population) gather along Nebraska's Platte River, though only about 1% of the ecoregion is protected.

Cross-Timbers savanna-woodland
The Cross-Timbers savanna-woodland — the post-oak / blackjack-oak savanna belt running roughly southwest-to-northeast through central Texas, central Oklahoma, and southeastern Kansas. Forms the ragged forested western edge of the eastern hardwoods before the Great Plains take over to the west. Heavily fragmented by agriculture and urban Texas / Oklahoma metro growth.
