I am told that most of the ash in the Glebe are green ash (Fraxinus pennsylvanica).
This is said to be a hairless version of red ash. But there are hybrids and the
City of Ottawa arborists now consider them equivalent. (2009).


Similar species
Red elderberry and elder: these also have opposite, compound leaves. They do not grow as tall as ash, and do not have
the diamond pattern on mature bark. Flowers are very different.
Mountain ash, butternut, black walnut, honey locust and sumac all have compound leaves but in an alternate pattern.
