It features a straight trunk and spreading crown. At the seedling stage，its stems are light green with elliptical lenticels. Mature trees have elliptical crowns. The petioles are light-red and the leaf bases are heart-shaped. Its mature catkins are less than 10 cm in length，with an anther dehiscence rate of less than 2.3%，resulting in little pollen release. It exhibits vigorous growth，with an afforestation survival rate over 98.3%. It shows strong resistance to leaf rust，brown spot and sooty mould，and is suitable for planting in the North China Plain.
