blue ash

Blue ash (Fraxinus quadrangulata) is a species of ash tree native to the central and southern United States. It is characterized by its bluish-green foliage and hard, brown wood. Ash trees, belonging to the genus Fraxinus, are found primarily in the Northern Hemisphere and are known for their timber and aesthetic value.12

These trees typically have pinnately compound leaves with an odd number of leaflets and produce winged, one-seeded fruits called samaras. While many ash species are valued for their strong and resilient wood, used in items like baseball bats and tool handles, they are also vulnerable to pests and diseases such as the emerald ash borer and ash dieback.2
