Ohio Department of Agriculture Invasive Plant List
May 15, 2018 
In order to protect native plant species and thwart the growth of invasive plant species, 38 plants have been declared invasive in Ohio. No person shall sell, offer for sale, propagate, distribute, import or intentionally cause the dissemination of any invasive plant in the state of Ohio.

Callery pear (Pyrus calleryana) can be sold until January 2023.

Shipments to other states:
Many other states also have regulations prohibiting or restricting the sales of certain plants that have been deemed to be invasive or noxious.  Please check with your nursery inspector if you have questions about shipping plants out of Ohio and to ensure you have the most current lists of prohibited invasive plants.

A five-person invasive plant advisory committee will review potential future additions to the invasive plant list.
