Paired samaras drop in autumn rather than spring as silver maple's do, and they germinate readily in mulch beds and gutter troughs. The fall leaves are large and come down in a short concentrated window, and any late-winter wound will drip sap that spots vehicles parked beneath.
Matures at 60–80 ft with a 50–60 ft rounded crown and lives roughly 150–200 years in decent soil. Full-size specimens carry dense heavy wood across a wide spread, putting them in a high removal bracket, and the tight crown means considerably more rigging than the height alone would suggest.
