The Blue Ash is a tall tree (70 feet) and has a bole diameter of two feet or more. The trunk is whitish with scaly bark. Leaves are ten inches long and hairless and lighter green underneath. They are toothed and concave into the main vein. The twigs are gray, hairless with square cross-section and have short brown pointy buds. The seed pods are singlet wings with square tips and are about five inches long. Flowers are small and green-to-purple and hang in dense clusters from leaf scars.

The growing region is from Arkansas to Ohio. The "blue" name comes from the dye that can be made from the inner bark. Ash is a hardwood tree which provides ornamental value to many homes and city residences. The wood is used for furniture, baseball bats and baskets. The bark and seed pods are used as a food supply by deer, porcupine and birds. Native Americans used the sap to make a bitter-sweet sugar.
