    The roots had a big mass like a large mat but did go about 3 inches deep. So it was a pretty big root ball and area.

    Well those seed pods are a dead giveaway. It is a bittercress (Cardamine) a member of the cabbage family. They are generally very invasive little blighters, they can grow, flower & seed all year round and the seed pods are explosive and will scatter seed all over the greenhouse.

    Now that I've seen the bigger pics, I think I had a little seedling in one of my capensis pots that I just pulled up today. Even as tiny as it was, it had a long root. Anything that is a weed, get rid of it! They usually reproduce prolifically and cause problems.

    gardenofeden,

    I'm sure you are correct. I have a friend who narrowed down to the family Brassicaceae (Mustard) today. Seeing your post now reconfirms it. Thank you very much for solving this mystery.

    BTW, my bittercress plant only had roots about 1 inch long, and it came up quite easily. On the other hand, the D. capensis had 5 inch long roots and the entire medium lifted up when I yanked/transplanted it out. Which one is the bigger weed?!
