Questions people ask
Why do these flowers bloom so early at Indiana Dunes?
Many are spring ephemerals: they race to finish their life cycle before the trees leaf out and shade the forest floor. The park's education page gives mid-April through May as the best time to see them in bloom.Source: National Park Service, Heron Rookery exploration (Indiana Dunes) ↗ (opens in a new tab)
Can I pick the wildflowers at Indiana Dunes?
No. Stay on the official trail and leave the flowers where they are; removing plants is prohibited.Sources: National Park Service, Heron Rookery exploration (Indiana Dunes) ↗ (opens in a new tab), National Park Service, Indiana Dunes: Heron Rookery Trail ↗ (opens in a new tab)
