It establishes fast, holds a dense, upright form, and offers outstanding — near-immune — resistance to Dutch elm disease, making it a dependable street-tree alternative wherever the old American elms were lost. Hardy through USDA zone 3 and tolerant of tough urban conditions, it's a low-risk workhorse.
