Green Ash

The Green Ash is the most widely distributed ash tree in North America. It is used to make furniture, furnishings, and tool handles and can grow to over 100 feet tall. The scientific genus, “Fraxinus,” means 'spear' in Latin, referencing the tough, elastic wood of the tree that was used to make spears and bows in the old world. The Green Ash was given its species name, “pennsylvanica,” because it was first classified in Pennsylvania. The Ash trees’ leaves also turn a beautiful golden color in Autumn.
