The first photo is one I posted a few weeks ago of a new weed in my garden. No one could identify it, especially without a flower. I've been pulling quite a few since and wondering where they came from. Well - now I know! I was over at my absentee neighbour's to help another neighbour (with permission) pull the forest of euphorbias on the property. There, in front of the deck, were dozens and dozens of the same plant in my picture, all grown up. Many had already released their dandelion-type seeds. I hope this is enough information to allow someone to ID it. I've been looking and have not found it yet. Note: I'm wondering about the plants in front of the lattice, not the daisies.
