Chinese and Siberian Elms (Ulmus parviflora & U. pumila)
These Asian natives were introduced in the 1860’s for their hardiness, fast growth,
and adaptability and are still sold as shade and windbreak trees. Their quickly developing
fruits can be dispersed by wind away from landscape plantings, and
grasslands and stream banks are vulnerable to infestation. The trees are classified
as invasive in 25 states, including Virginia.
