Can anyone help me ID this? I have a small patch of earth outside my townhouse in Baltimore. Small sidewalk square sized. I scattered a bunch of different seeds this spring. These are everywhere (mixed in with Mexican sunflower) but they just seem to get taller and taller. No flowers yet. This one is small/medium sized. I want to pull of weeds but don't if they just haven't flowered. I can say that the leaves don't look like anything I planted from the seed packet covers. Thanks!!!!
