I don't know what flower this is, but it is green, growing, and wasn't there a few days ago! Mark scattered seeds at the end of last summer in the spot, and some of them grew and bloomed. This is probably from the seedhead of one of those. There was an echinacea close to here but I don't believe those spread by seed. It is not one of my carnations, those have thinner leaves. So I will have to take a picture several weeks from now when this is grown and has bloomed. But until then, I will just enjoy this promise of spring!
