?your area's worst invasive plant?

[Woodpecker52]

Barabas bush takes over fields has white wind blown seeds, leaves smell like pungent  wet dog,  plant came from somewhere around eastern Europe just another @#@! hole plant like kudzu edited by admin  up the southern eco.  No telling what else will be loused  on us from abroad, lets see chestnut blight, dutch elm, fire ant, emerald ash borer, flying carp, Burmese python, mimosa, and on and on and on.  I am surprised they haven't put snakes in Herwayall yet.

North American plants...things like Canada goldenrod...are spreading around Europe and elsewhere.  Not a one-way phenomenon.
