35 Illinois Landscaping Ideas for Chicago, Springfield & Downstate IL
The Prairie State has some of North America's toughest winters and most beautiful native plants. Prairie-inspired landscapes, Chicago urban designs, and deer-resistant options for every IL region.
Chicago Metro & North Suburbs (Zones 5b–6a)
Brutal winters (-20°F in cold snaps), hot humid summers (95°F+), 38" rain + 38" snow annually, lake-effect modification near Lake Michigan, strong winds year-round
Chicago Townhouse Urban Garden
For Chicago's dense row homes and townhouses: vertical green walls, raised planter boxes at deck edges, compact dwarf trees (serviceberry, 'Spring Snow' crabapple), and container gardens that can be brought inside before -20°F cold snaps.
North Shore Prairie Conversion
A front yard conversion for North Shore suburbs: replace lawn with a managed prairie planting of little bluestem, prairie dropseed, purple coneflower, and rattlesnake master. Monarch waystation certified, HOA-friendly with neat mown edge.
Chicago Modern Backyard
A sleek Chicago backyard with concrete pavers, steel planters, ornamental grasses, and a few strategic specimen trees: 'Heritage' river birch for 4-season bark interest, 'Royal Purple' smokebush for drama.
Lakefront Chicago Design
For properties near Lake Michigan, salt and wind tolerance is critical: Rosa rugosa hedge handles lake spray, Siberian iris, rugosa roses, and beach grass stabilize slopes. Spectacular in summer bloom.
Chicago Suburbs — DuPage & Will County (Zones 5a–5b)
Coldest zone in the Chicago metro — zone 5a in west suburbs. Heavy clay soil (Wheaton, Naperville), suburban lots with HOA requirements, significant deer pressure
DuPage County 4-Season Garden
Designed for suburban IL's dramatic seasons: spring bulbs (daffodil, not tulip — deer resistant), summer daylilies and black-eyed Susan, fall 'Autumn Joy' sedum and asters, winter red-twig dogwood and crabapple fruits.
Naperville Deer-Resistant Landscape
DuPage has extreme deer pressure. This design uses unpalatable plants: daffodils (deer hate them), catmint, baptisia, yarrow, and Russian sage. Fencing around any edibles. Reliably beautiful even with heavy deer browsing.
Suburban IL Shade Garden
Many older Wheaton/Naperville homes have large mature oaks creating dense shade. Best performers: hostas, astilbe, ferns, Solomon's seal, and native wild ginger as groundcover. Spring ephemerals (bloodroot, Virginia bluebells) fill in before leaf-out.
Suburban Rain Garden
Illinois receives 38" of rain in intense spring/summer events. A rain garden handles overflow: cardinal flower, swamp milkweed, blue flag iris, and native sedges absorb runoff while attracting monarchs and hummingbirds.
Central Illinois — Springfield & Peoria (Zone 5b)
True Midwest continental: hot summers (100°F), cold winters (-10°F), flat terrain, rich loam soil (some of the world's best agricultural soil), tornado-prone corridor
Springfield Prairie Landscape
Illinois is 'The Prairie State' — celebrate it. A tallgrass prairie planting of big bluestem (state grass), Indian grass, prairie blazing star, and compass plant creates a stunning 6-foot-tall summer display.
Central IL Farmhouse Garden
For Central Illinois farmhouses and rural homes: a classic cottage/farmhouse garden with zinnias, sunflowers, peonies, and climbing roses on a split-rail fence. Old-fashioned, low-maintenance, beautiful.
Lincoln Home Heritage Garden
Springfield's connection to Abraham Lincoln: a 'Lincoln's Garden' with plants from the antebellum era — heritage roses, heirloom lilacs (still blooming from 1800s plantings), iris, and hollyhocks.
Wind-Resistant Central IL Design
The flat prairie generates powerful sustained winds. Wind-tolerant design: low-growing ornamental grasses that flex, dwarf shrubs under 4 feet, no tall specimen trees near structures, windbreak shrub rows on north/west edges.
Southern Illinois — Carbondale & Metro East (Zone 6a–6b)
Warmer zone 6b near the Kentucky border, Shawnee National Forest region, more humid and lush, longer growing season, unique mix of Midwest and Southern plant palette
Shawnee Forest Native Garden
Southern IL's Shawnee National Forest is a biodiversity hotspot: wild azalea (Rhododendron prinophyllum), trout lily, bloodroot, and pawpaw form a stunning Ozark-influenced woodland garden.
Southern IL Extended Season Garden
Zone 6b allows Southern IL homeowners to grow plants Chicago cannot: gardenias in protected spots, crape myrtle reliably, figs, and semi-tropical cannas and elephant ears that can be left in ground with heavy mulch.
Metro East Suburban Classic
A traditional suburban landscape for Belleville, Edwardsville, and the St. Louis metro: flowering crabapple + dogwood in spring, sweeps of daylilies in summer, 'Autumn Blaze' maples for fall color.
Carbondale Native Shade Garden
A lush shade garden inspired by the Cache River wetlands: native ferns, cardinal flower for hummingbirds, Jack-in-the-pulpit, and woodland phlox as spring blue carpet under tulip poplars.

Illinois prairie natives evolved for the region's extremes: -20°F winters, 100°F summers, drought, and flood. They require zero irrigation after year 2.

Illinois Landscaping FAQs
What are the best native plants for Illinois?
Illinois is 'The Prairie State' and has one of the richest native plant traditions. Best performers: big bluestem (state grass), purple coneflower, prairie blazing star, black-eyed Susan, wild bergamot, rattlesnake master (unique texture), serviceberry, and compass plant. Illinois native plants survive -20°F winters, 100°F summers, and drought — they evolved here over 10,000 years.
How do I landscape Chicago's small urban lots?
Chicago's 25-foot-wide lots require vertical thinking: (1) Use wall-trained espaliered trees or climbing plants on south-facing walls, (2) Raised beds maximize small spaces, (3) Choose compact cultivars — dwarf Korean lilac instead of standard (3 ft vs 10 ft), (4) Build up, not out — second-story deck gardens, container walls, green roofs, (5) Use reflective light-colored hardscape to brighten narrow dark spaces. Chicago has excellent community gardens for those with no yard space.
What plants survive Chicago's brutal winters?
Chicago zone 5b can hit -20°F with windchill below -50°F. Proven survivors: river birch, serviceberry, hawthorn, rugosa roses, Siberian iris, daylilies, Karl Foerster grass, arborvitae 'Green Giant', Korean lilac, forsythia, and virtually all Illinois natives. Avoid: Japanese maples (need zone 6+), crape myrtles (zone 7+ reliably), most broadleaf evergreens. Zone 5b is manageable — hundreds of beautiful plants thrive.
How do I deal with deer in suburban Illinois?
DuPage, Will, and Lake counties have significant deer pressure. Most reliable protection: (1) Physical fencing — 8 feet tall for vegetable gardens, (2) Deer-resistant plants (daffodils, catmint, baptisia, yarrow, ornamental grasses, fragrant herbs), (3) Spray repellents — rotate scents monthly so deer don't habituate, (4) Motion-activated sprinklers, (5) The only truly deer-proof plant: none. But deer consistently avoid fragrant, thorny, and toxic plants.
How do I start a prairie garden in Illinois?
Starting a prairie garden in IL: (1) Test your soil — most IL soil is excellent for natives already, (2) Remove existing grass with cardboard mulch layering (no-till) or smothering tarp method in fall, (3) Seed in fall (most prairie seeds need cold stratification) OR plant plugs in spring, (4) Mow to 6" once in year 1 to set back weeds, (5) Years 2–3 are when prairie plants bloom significantly (they spend year 1 building deep roots), (6) Annual late-winter burn or mow (February) resets prairie cycle. Contact the Illinois Native Plant Society for seeds.
