Introduction: This is an upland species that typically grows 50-75’ tall with a narrow, irregularly rounded crown. Clusters of apetalous bisexual purplish flowers appear in April-May with the foliage. Flowers give way to drooping clusters of winged samaras (to 2” long) that ripen in fall and may persist on the tree throughout winter. Features odd-pinnate compound leaves, each with 7-11 lance-shaped, dark green leaflets (4-5” long). Leaves turn pale and usually dull yellow in fall. Grayish bark on mature trees separates into irregular plates. As with white ash, the wood of blue ash is commercially used for a variety of products including tool handles and furniture.

Distribution: Native to North America.
