I HATE THIS STUFF !! You're absolutely right about what a pain-in-the-posterior this weed is deal with. I just found this post while trying to figure out what this and some other noxious weeds were. Have you noticed it's really stinky when you pull it ? The stench is enough to make me gag after a while. I apologize if that was too much info. I'm afraid this stuff just makes me nuts. ;)
