Black Ash (Fraxinus nigra) — Native Wetland Tree Saplings for Restoration, Shade & Riparian Sites

The Black Ash (Fraxinus nigra) is one of North America’s most valuable and adaptable native trees, especially for wet and shaded landscapes. If you’re restoring land, stabilizing a streambank, creating a wetland buffer, or expanding a native food-forest canopy, Black Ash is a strong, reliable, and ecologically rich choice.

Why Black Ash?

Black Ash stands out for its rare ability to thrive in wet, heavy soils where most trees struggle. Its roots tolerate seasonal flooding, marshy patches, and riparian zones, making it a top performer for restoration projects and erosion control. With a moderate-to-fast growth rate and a mature height of 40–60 feet, it forms a beautiful rounded canopy that cools, shelters wildlife, and improves ecosystem stability.

Where Black Ash Grows Best (Zones & Conditions)

Black Ash naturally grows in USDA Zones 3–6. It performs best in cool climates, wet grounds, and shaded areas, especially:

• Riparian edges

• Moist woodlands

• Floodplains

• Swales & low-lying drainage spots

• Pond edges & naturalised native landscapes

If your land has wet soil where nothing else grows well — Black Ash will.
