White Ash (Fraxinus americana) vs. Green Ash (Fraxinus pennsylvanica)
Updated June 23rd, 2020White and green ash are notoriously difficult to tell apart. White ash prefers better-drained sites with more fertile soil, but the two species often occur in the same habitat. Characteristics like leaf shape and serration are highly variable on both species; with skill though, the two species can usually be distinguished at any time of year. Some trees are easier to identify than others. Because of high variability, check multiple examples of each characteristic before drawing a conclusion.
