Botanical Name

FRAXINUS pennsylvanica 'Patmore' PP4684

Plant Common Name

Green Ash, Patmore Green Ash

General Description

Female green ashes produce copious messy winged fruits but the male 'Patmore' stays clean and seed-free. It is also exceptionally hardy and has lustrous deep green leaves and yellow fall color.

Green ash is a tall, vigorous deciduous tree with a bushy 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 glossy and dark green. These have opposite arrangement and commonly turn yellow in autumn. Ashes flower early in the season, but the blooms are inconspicuous.

Green ash grows best in locations with full to part sun. It is widely planted, and makes a great shade tree or street tree for urban settings. Avoid planting ashes where emerald ash borer has become a problem.
