I had the same thing happen to me last year. It was on one of my best seedlings and I was tickled to death to have that many babies coming up. Weeeeeellllllll you know the rest of the story. It started growing a little branch off to the side of the blade of the daylily fan and I quickly dug the whole big clump up and was told it was nutsedge and that it was. Burst my bubble, it did. Mine was in a pot, so I quickly dispatched that clump of weed to the garbage bag. Darn stuff, sure can fool you into thinking you've hit the jackpot for seedlings.
