What NOT to Plant

Following is a list of plants to avoid. You’ll see many of them in established gardens, introduced into the nursery trade as ornamental landscape plants. Unfortunately they’re running amok in our natural areas and crowding out native vegetation.

We encourage you NOT to buy or plant these plants, and to urge your local nursery or garden center NOT to sell them.

This is just a partial list, covering some invasive plants common to home landscapes and woodlots. A comprehensive listing of problem plants is here: Indiana Invasive Species Council Plant List.

INPAWS is piloting an incentive program that encourages retailers to sell native plants and NOT sell invasives: Grow Native Program.
