About this species

Fraxinus americana is a rapidly growing tree suited to parkland plantings, where cultivars selected for yellow, orange or bronze autumn colour are highly valued.

The timber has readily marketable qualities – it is hard, heavy, and shock-resistant and used extensively for tool handles, baseball bats, furniture and also as fuel wood. Native Americans used different parts of the plant for a variety of medicinal purposes including relief from insect bites, cure for fevers, an aphrodisiac, and appetite stimulant.

The tree supports a wide variety of wildlife in its native North America, and the tendency of the trunk to form cavities makes it ideal for woodpecker nesting holes. Larger cavities may be used by owls, wood duck, nuthatches or grey squirrels.
