Native to southeastern Minnesota, white ash grows best in rich, moist soil. The wood is strong and elastic. Uses include baseball bats, tool handles, and furniture.

While other trees, such as mountain ash and prickly ash, have "ash" in their common name, they are not true ash, or Fraxinus species. Only true ash are susceptible to attack by emerald ash borer.
