Report an issue with this species
The American Elm is a stately tree with a broad, arching canopy, deeply furrowed grayish-brown bark, and leaves that turn yellow in the fall. Native to eastern North America, it was historically popular as a street tree due to its urban tolerance, though its populations were severely impacted by Dutch elm disease. It is a versatile species, thriving in various soil conditions and providing ample shade.
