Quick facts

Tree of heaven is a Restricted noxious weed and is considered an early detection species not present or with a limited distribution in Minnesota.

  • Tree-of-heaven grows well in a variety of soil types and tolerates varying soil moisture conditions, allowing it to grow quickly and colonize disturbed areas.
  • It grows well in urban areas and is a host for the invasive spotted lanternfly.
  • Roots are allelopathic, producing chemicals that prevent the germination of nearby plants.

Tree-of-heaven should be reported. The Minnesota Department of Natural Resources provides detailed recommendations for reporting invasive species.
