Plant (weed?) ID Please

    About 50-60 of these sprung up in the last couple of days, growing 1-2 inches/day (now about 9-10 inches high) with all the alternating rain and sun we've been having. They showed up in a bed of marigolds. The leaf structure is finer, more whispy, and these are growing much faster and taller than the marigolds, which makes me suspect that they are some sort of weed. Any ideas out there. The shot was taken with an Olympus E-PL2 and a 105mm/2.8 Micro Nikkor.

    A weed...? Lets not get into definition of what a weed is. Your family is the Brassicaceae (old Cruciferae) IF you are in the continental US, good chance that it is Cardamine concatenata (Cutleaf toothwort).

    Yes Rick, I'm in the northwestern suburban Chicago area. Thank you.
  4. Hope that helps :)
  5. I think it's awfully late for cutleaf toothwort - those bloom in early to mid-April. It does look like something from the mustard family, though.
