INDIANAPOLIS (The Indianapolis Star) — Indiana has banned the sale and exchange of nearly four dozen invasive plants that pose a threat to the state’s native plants and animals.

The Indianapolis Star reports that the rule took effect April 18 banning 44 species of invasive plants, including five different species of honeysuckles that eventually choke out surrounding plants.

Among other banned plants are the Japanese barberry and Wintercreeper.

The plants can still be owned.
