Blue Ash, Fraxinus Quadrangulata

/Home/Garden Basics/Trees/Types of Trees/Ash Trees/Blue Ash Trees

The Blue Ash derives its name from pioneers extracting a blue dye from its inner bark. It is native to part of the Midwest and upper South in MO, IL, IN, OH, KY, and TN. It is not widely distributed in its native range, but is only found in certain areas of very alkaline soils, usually upland. Some big conventional nurseries in the Midwest offer some plants of this species, though it is not nearly grown or sold as the very popular White Ash or Green Ash species. Native nurseries often offer this species around its native area. It is good for USDA zones 4 to 7.
