This tentative map is based on our own research. It may have limited data on Canada and/or Mexico, and there is some subjectivity in our assignment of plants as introduced vs. expanded. Read more in this blog post.

Although this plant occurs somewhere in each of these regions, it may only occur in a small part of some or all of them.

This species is occasionally used in landscaping; it is less likely to colonize disturbed habitats than other ash species. BONAP reports the Florida population as adventive, which we mark as expanded because of its proximity to the native range, but it could perhaps be marked introduced if it is established from landscaping escapes. We have not researched the details of this population so please contact us if you have clarification about its origins.
