September elm (Ulmus serotina), also called red elm, is one of two fall-flowering native elms. This medium-sized, rapid-growing tree is found most frequently on moist clay or sandy loam soils, but it also grows on dry, rocky soils of limestone origin. It is never abundant and in early development it is an inconspicuous understory component of hardwood stands. This species may appear more frequently within its range than is currently documented because it may be confused with other elm species. The lumber is cut and sold with four other elm species and marketed as rock elm. Wildlife browse young trees and eat the seeds and buds. September elm is planted in landscapes but succumbs to Dutch elm disease.
