This is the thornless version of the species. It is a popular street tree in the East and Midwest and offers a graceful habit and fine textured leaves that can be spectacular in their rich golden yellow fall color. The light shade the bright green summer foliage casts allows grass to grow next to the trunk. It is very adaptable to soils and displays excellent salt tolerance.
