The ash tree is mostly cultivated, with a long history of cultivation and wide distribution in China. It is also found in the forests of mixed trees in the mountains at an altitude of 800-1600 meters. The plant is strong in sprouting, straight, fast-growing, soft and tough, and is used for the preparation of all kinds of utensils; the bark is also used for medicine.
