A Note on Invasive Wildflowers

The Indiana Dunes are home to so many beautiful wildflowers. Unfortunately, not all of them belong here. Over the years, non-native species have taken root in the region, crowding out native species that are crucial for supporting fragile ecosystems. The parks, non-profit organizations, and volunteers work diligently to restore these areas.

If you spot an invasive species, please leave it be: it takes careful oversight to remove these plants without damaging the area, and poison ivy, ticks, and sometimes even toxins from the plants themselves can be a hazard.


These purple flowers are part of the sunflower family. Although they may look lovely, they are invasive, crowding out native plants. They are thought to have been brought over from Europe in the nineteenth century.

Oriental Bittersweet

This vine is native to Asia, and it has small greenish flowers that are replaced by bright reddish-orange berries. With its bright berries, it was once popular both for gardens and decorating, but its vines can spread quickly and choke native trees.

Purple Loosestrife

With multiple purple flowers growing from a tall spike, the purple loosestrife was brought over from Europe in the nineteenth century as a colorful addition to gardens. This hardy plant poses such a danger to native wildflowers that its sale was outlawed in 1996.
