Plant Common Name

Green Ash

General Description

Green ash is a tall, vigorous deciduous tree with an oval to irregular spreading crown. This native of central and eastern North America is adapted to a wide range of soils and topographies, including wet sites.

Throughout the growing season it has attractive compound leaves that are often lustrous and olive or dark green. These have opposite arrangement and commonly turn yellow in autumn. Ashes flower early in the season, but their blooms are inconspicuous and dioecious, which means that separate trees have either male or female flowers. Only the female trees set fruit. The fruits are elongated, papery, have a single dry, brown wing and come in big clusters. These can be quite messy, so male trees are most commonly cultivated.

Green ash grows best in locations with full to partial sun. In the wild, it commonly grows in lowlands, so it will tolerate some soil moisture and will withstand a wide range of soil conditions. This is a classic large shade tree for open areas and street sides. It is also tolerant of salt and urban conditions. Avoid planting ashes where the emerald ash borer has become a problem.
