Blue ash is a deciduous tree native to the midwestern U.S.A. in the olive family (Oleaceae). The species epithet is Latin for “four-angled” and refers to the young twigs, which bear four longitudinal ridges or low wings giving the twig a four-sided appearance.
Blue Ash occurs primarily in east-central USA in Missouri, Illinois, Indiana, Ohio, Kentucky, and Tennessee. Habitats include upland deciduous woodlands, wooded slopes, thinly wooded bluffs, edges of limestone glades, and areas along limestone cliffs.
It is fast growing in lowland sites about 2 feet/year, but medium in upland sites of about 1 to 1.5 feet/year, and lives about 100 to 150 years. It makes a good shade tree with an interesting texture and it is occasionally grown by larger or native nurseries.
