Tree of Heaven (Ailanthus altissima)        

Also known as Chinese or Stinking Sumac, this plant was introduced from China
in 1784 as a specimen and shade tree. It was commonly found in nurseries by
1840 and has been popular in urban plantings ever since. This rapidly-growing
tree has now overwhelmed natural areas in over 30 states and is reported as
invasive in national parks on the east coast, including many in Virginia, Maryland,
and Washington, DC.
