This is about 2 months old. About 20" height. It started out with three leaf fans then went to 1 leaf. and has stayed there for about three weeks. I am starting to see some three leafs come back, but the question is, what the heck is this thing? I sprouted it from a random seed I found while moving.(found several, but only three got more than a few inches tall then stopped and turned yellow). I assume it is some sort of ruderalis but not sure. And, what is it doing? The branches are very bushy, sparse calyx.
