Have you seen tree of heaven plants in your neighborhood? This fast-growing invasive tree is easy to identify and found all over NY, particularly in urban areas. Tree of heaven (Ailanthus altissima) is the preferred host plant of the spotted lanternfly, an invasive insect being found in more and more parts of NY that could have severe impacts on our state’s agriculture and forests. Finding and reporting tree of heaven to NY iMapInvasives can help supplement state efforts to prevent negative impacts from these two species.

Plant and leaflets resemble sumac. TOH leaflets are smooth around the edges with a small notch at the base (see top photo), whereas sumac leaflets have jagged edges.When touched or broken, TOH has a unique scent similar to burnt peanut butter.You can find more information, including photos to help with identification, on the Penn State Extension website.If you find TOH on your own property, you may be interested in removing it.
