Had this plant of questionable charachter volunteer in one of my pots.
SOLVED: Unfriendly-looking unknown
Gotta be one of those Prenanthes sp. that you couldn't ID before...
VV - I can't believe it. Check out this link, 6th photo down. http://ontariowildflowers.com/main/species.php?id=528 What was the giveaway? Alternate leaves? You deserve some chocolate truffles, even if you got lucky while yanking my chain. It may well be Prenanthes altissima, but I'll leave this up a while to see if there are any added comments.
Blind pig...turnip...or truffles.
Ask not what DG can do for you, but what you can do for DG.
It looks a lot like Lapsana communis, a weed from Europe. I'm not going to mention the common name, in case I upset anyone.
It looks like the common Sowthistle that grows around here.
