Ohio

Approximately one-fourth of the plant species known to occur in Ohio originate from other parts of the continent or the world, meaning they are not native to the state. Most non-native plant species are not invasive in natural areas. Of the more than 700 non-native plants in Ohio, fewer than 100 are known to be problems in natural areas. But, those that are invasive can cause extensive economic damage and do immeasurable harm to our natural resources and the natural heritage of our state.
