Black Ash

Fraxinus nigra

Black Ash (Fraxinus nigra) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 65 ft at maturity and blooms in early spring. Match it to full sun to part shade and keep the root zone consistently moist. One caveat: like any plant, its published range is a guideline, not a guarantee, for the specific microclimate of your yard. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
