Mile-a-minute weed (Polygonum perfoliatum) is another vine capable of rapidly forming a dense canopy over trees. It negatively impacts natural areas and forest plantations in the mid-Atlantic states and has been spreading rapidly since its accidental introduction to the US in the 1940s. It is shown here overtopping young trees in a forestry plantation in southern Pennsylvania.
