What is it? Friend or foe?

Sure hope I don't regret pulling these suckers. Anyone have any idea what it is? Go ahead and take the poll - extra points if you can name it.

Memory of a fern

Given my ability to hold a botanical image in my head (that is I can't) I'm hoping that by posting to this blog I'll be able to look back next year and learn what is a weed.

OH, wait... these are the same suckers we had in "friend or foe!"
