Fraxinus quadrangulata, or Blue Ash, is an impressive species primarily native to the American Midwest. The tree's 'blue' comes from a substance secreted by its inner bark, not its dark green leaves that turn pale yellow in the fall. The inner bark is ground to produce a blue dye, explaining the origin of the plant's name. Favoring limestone substrates, Blue Ash thrives in moist valley soils and on limestone slopes from the elevations of 400-2,000 ft. With its tolerance for drought and lime, it could be a good candidate for a street tree. Blue Ash is an important medium-sized tree, reaching a height of 30-80 ft with twigs having a unique square appearance due to its four corky ridges. Unlike Black and Green Ash species, approximately sixty to seventy percent of Blue Ash trees survive the infestation of the emerald ash borer, an invasive beetle.
