I planted a bunch of herb seeds in my tiny urban backyard garden this spring, and I thought I was growing a whole bunch of parsley until I realized it's not parsley. I ate some of it - it doesn't taste like much, but it hasn't killed me yet, either. I have stopped eating it, though. The picture has a leaf of confirmed parsley on the left with whatever I'm growing on the right. The flower is from a neighboring plant. I haven't seen this weed in any other place in my neighborhood, so I don't know what it is, where it came from or how it's growing so fast! Help, anyone?
