This popped up in my garden, which was formerly part of one of our hay fields. It's strange looking! I've got another one that I'll post next that looks very similar, but different enough that it may be a different weed.
This one is growing in bark that is on top of weed block, so it must have started from seed. I was thinking at first that it could be a spurge, but there is no milky sap when I break it apart. This particular plant is 9 inches across, but I doubt that it is done growing. I can't find one that is blooming, so I'm not sure what colors the flowers are. I'll keep checking on it though.
