Short answer
What growing zone is Peoria in?
On the current USDA hardiness map, the Illinois River areas of Peoria and Tazewell counties moved up to zone 6a, according to University of Illinois Extension. Northern Peoria County, including the Dunlap area, stayed in zone 5b. To be safe, choose plants rated to zone 5, so they survive a harder-than-average winter.
Full sun
Sunny beds
| Type | Good choices | Why |
|---|---|---|
| Perennials | Purple coneflower, black-eyed Susan, catmint, daylily, sedum | Handle heat and clay; long bloom |
| Grasses | Little bluestem, switchgrass, prairie dropseed | Low care; winter interest |
| Shrubs | Ninebark, spirea, potentilla, shrub roses | Tough, compact options |
| Small trees | Serviceberry, redbud | Spring flowers; size fits most yards |
Shade
Shade under mature oaks and maples
| Type | Good choices | Why |
|---|---|---|
| Perennials | Hosta, coral bells, astilbe, wild ginger | Thrive in shade; fill space |
| Ferns | Ostrich fern, Christmas fern | Texture where little else grows |
| Shrubs | Hydrangea (smooth and oakleaf), viburnum | Flowers in part shade |
| Groundcover | Woodland phlox, sedges | Replace thin grass under trees |
Wet spots
Soggy areas and rain gardens
| Type | Good choices | Why |
|---|---|---|
| Perennials | Swamp milkweed, blue flag iris, cardinal flower | Like wet feet |
| Grasses and sedges | Switchgrass, sedges | Hold soil; tolerate flooding |
| Shrubs | Red twig dogwood, buttonbush, chokeberry (aronia) | Handle wet clay |
See fixing drainage in clay soil first if water sits for days.
Avoid
Plants to think twice about
- Burning bush and Callery (Bradford) pear: both are invasive in Illinois and spread into natural areas.
- Ash trees: emerald ash borer has killed huge numbers across Illinois.
- Plants rated only to zone 6 or 7: a hard winter can wipe them out.
- Shrubs that outgrow the spot: check mature size before planting by the house.
FAQ
Plant questions
When is the best time to plant?
Early fall for trees and shrubs, and spring once the ground dries. See planting.
Do native plants grow better here?
Natives are adapted to Illinois clay and weather, so once established they usually need less care. See native landscaping.
What grows in heavy clay?
Most plants in this guide handle clay. Planting at the right depth matters more than amending the whole bed.
