Information on Ash Trees

How to Identify an Ash Tree

Branch and Bud Arrangement - Branches and buds are directly across from each other and not staggered. When looking for opposite branching in trees, please consider that buds or limbs may die; hence not every single branch will have an opposite mate.

Leaves - Leaves are compound and composed of 5-11 leaflets. Leaflet margins may besmooth or toothed. The only other oppositely branched tree with compound leaves is boxelder (Acer negundo), which almost always has three to five leaflets.

Bark - On mature trees, the bark is tight with a distinct pattern of diamond-shaped ridges. On young trees, bark is relatively smooth.

Seeds - When present on trees, seeds are dry, oar-shaped samaras. They usually occur in clusters and typically hang on the tree until late fall, early winter.
