Overview
Ohio's wildflower year begins with spring ephemerals blanketing the hardwood forests, then moves into prairie and wetland flowers through summer and fall. The large-flowered trillium is the state's official wildflower.
This guide covers common and iconic Ohio wildflowers — how to recognize them and when they bloom. Photograph the flower and leaves and use the app to confirm any bloom you find.
Key Species to Know
Large-flowered Trillium
Trillium grandiflorum
Ohio's state wildflower — three broad white petals above a whorl of three leaves, fading to pink with age. Forms sweeping colonies on the spring forest floor.
Virginia Bluebells
Mertensia virginica
Nodding clusters of sky-blue, trumpet-shaped flowers (pink in bud) over smooth gray-green leaves, forming blue drifts on damp spring floodplains.
Wild Columbine
Aquilegia canadensis
Nodding red-and-yellow flowers with backward-pointing spurs, dancing on thin stems over lacy leaves. A hummingbird favorite of rocky woods.
Wild Bergamot
Monarda fistulosa
A mint-family wildflower with ragged, lavender pom-pom flower heads and a minty scent, humming with bees and hummingbirds in summer prairies.
Cardinal Flower
Lobelia cardinalis
Tall spikes of intense scarlet, tubular flowers along late-summer streambanks — one of the most vivid reds in the eastern flora. Pollinated by hummingbirds.
Black-eyed Susan
Rudbeckia hirta
A familiar daisy with golden-yellow rays around a dark brown dome, common in meadows and prairies. Bristly stems and leaves.
Seasonal Guide
- April–May: spring ephemerals — trillium and bluebells — carpet the woods before the canopy closes.
- June–August: prairie and meadow flowers such as bergamot and black-eyed Susan peak.
- Fall: cardinal flower, asters, and goldenrods close out the season.
Safety Reminder
Many spring wildflowers, including the state's trilliums, are slow-growing and protected — enjoy and photograph them in place rather than picking or digging. This guide is for identification and enjoyment, not foraging.
