Fraxinus quadrangulata, or blue ash, is recommended for planting compared to other ash species, but with caution. Research has indicated this species is less susceptible to emerald ash borer than other ash species. Native to central North America, specifically from southwestern Ontario and Michigan to southern Wisconsin, south to West Virginia, Georgia, Alabama, and west to Kansas and Oklahoma. Blue ash thrives in dry to medium wet, well-drained soils and is one of the most tolerant ash species for dry sites. It gets its name from the blue dye that can be extracted from its inner bark. Historically valued as a shade, street, and lawn tree, its adaptability is overshadowed by green ash.
