American ash is a large native deciduous tree with an upright, oval crown and compound leaves that turn yellow to purple in fall. It produces small, inconspicuous flowers in spring before the leaves emerge. This stately tree was once common in New England landscapes but has been severely impacted by the invasive emerald ash borer beetle.
