Illinois is "the Prairie State," and its wildflowers tell that story. On the restored tallgrass prairies, summer brings a sea of color — purple blazing star, orange butterfly weed, pink bee balm, and golden black-eyed Susans buzzing with bees and butterflies. In the spring woodlands, the forest floor fills with delicate trillium, bloodroot, and marsh marigold. From rare fens to ancient woods to the great prairies, learning the wildflowers turns any Illinois walk into a discovery.
This guide maps the best spots to find wildflowers in Illinois with kids. Give your young explorer a mission before you go with Nature Explorer Club's Wildflowers of Illinois Activity Book to track every flower your family discovers.

Family Tips for Wildflower Exploring in Illinois
- Visit a tallgrass prairie in mid-to-late summer. Wolf Road Prairie and Goose Lake Prairie blaze with blazing star, coneflower, and bee balm in July and August — the real Prairie State in bloom.
- See the spring bluebells. Messenger Woods and other woodland preserves fill with Virginia bluebells and trillium in April — a magical sight for kids.
- Smell a bee balm leaf. Crush a leaf and it smells like a mix of mint and oregano — and the flower's nectar has twice the sugar of most blooms, which is why pollinators love it.
- Look, don't pick — and use iNaturalist. Wildflowers in preserves are protected (trillium can be killed by picking); bring a camera and the iNaturalist app to identify and record finds instead.
Frequently Asked Questions: Wildflowers of Illinois with Kids
What is the state wildflower of Illinois?
The violet is Illinois's state flower — a small woodland wildflower with heart-shaped leaves and purple-blue blossoms that bloom in spring. Illinois schoolchildren voted for the violet back in 1908. Its flowers are even edible, and they carpet woodlands and lawns across the state each spring.
Where is the best place to see wildflowers in Illinois with kids?
For spring woodland wildflowers, Messenger Woods and Starved Rock are spectacular with bluebells and trillium. For the famous prairie wildflowers, Wolf Road Prairie and Goose Lake Prairie are wonderful in summer, and the Morton Arboretum is great for families year-round.
When is the best time to see wildflowers in Illinois?
Spring (April–May) brings the woodland wildflowers — bluebells, trillium, bloodroot, and marsh marigold. Summer (July–August) is the peak for the famous tallgrass prairie flowers like blazing star, coneflower, and butterfly weed. With both, Illinois has wildflowers from spring through fall.
What is a tallgrass prairie?
A tallgrass prairie is a grassland where native grasses and wildflowers can grow taller than a child — sometimes taller than an adult. Illinois was once mostly prairie, earning it the nickname "the Prairie State," but very little original prairie remains today. Preserves like Wolf Road Prairie protect these rare wildflower-filled grasslands.
Are wildflowers protected in Illinois preserves?
Yes — picking or digging wildflowers in nature preserves and parks is prohibited, and some, like trillium, can be killed by picking. Enjoy them in place, take photos, and use an app like iNaturalist to identify and record what you find, so the blooms remain for wildlife and other families.
