I'll certify this BB complete but I don't think that's a dandelion...
Oh, that makes so much more sense! Do you have a suspicion of what it is? If it's not dandelions then I might not be able to use it in the seed bombs.
ETA: From what I can tell it looks like thistle. And given the state of the plant it's hard for me to identify whether it is a good or bad thistle. So I'll remove it from the seed ball candidates and plant a few in pouts to see what it is. Tall thistle is beneficial for pollinators. Monk thistle is a noxious weed.
