White ash, Fraxinus americana, is a large North American shade tree that reaches 50 to 80 feet or more, with compound leaves that turn purple, yellow, or red in fall. It grows wild across eastern and central North America, most often in forests alongside sugar maple, and is hardy in zones 3 to 9.

Why is white ash found mostly in forests?

Because it does best in deep, moist soil, the kind found on rich forest ground. Its close relative, green ash, is the species that colonizes stream banks and disturbed sites, which is one reason the two are often found in different places.

Where is white ash native?

Across much of eastern and central North America, from southeastern Canada south to northern Florida and west into the Great Plains states. Within that range it is a common forest canopy tree.

Is white ash still a safe tree to plant?

Only with a plan for emerald ash borer. White ash is very susceptible to emerald ash borer, a beetle from Asia whose larvae kill ash trees, and an infested tree usually needs removal or regular insecticide treatments.

What growing conditions does white ash need in a yard?

Full sun, deep and moist soil, and room for a crown 50 to 80 feet wide. It grows fast, and its leaves cast a light shade that lets other plants grow beneath it.

Where a yard offers that space and soil, American White Ash Seeds can be sown in a mulched bed in fall, the natural sowing option its listing describes.
