   Noxious Weed: "Any living stage (including but not limited to, seeds
   and reproductive parts) of any parasitic or other plant of a kind, or
   subdivision*'of a kind, which is of foreign origin, is new to or not
   widely prevalent in the United States, and can directly or indirectly
   injure crops, other useful plants, livestock, or poultry or other
   interests of agriculture, including irrigation, or navigation or the
   fish or wildlife resources of the United States or the public health."

I'm sure we all have a number of plants from that list.  

The departments of agriculture of individual states may also have their own
lists.  For instance, a list of Idaho's Noxious Weeds (all terrestrial,
AFAICT) is available at. <http://agri.state.id.us/isda/animal/weedlist.htm>.
