Doesn't match the pics of those two, and I hope its not poinsettia. Torts have eaten it before. Its a tough one. It was growing as a weed in the shade between two night boxes. It was very light and fragile. Delicate.Tough call. Reminds me of wild poinsettia (euphorbia sp.) which is toxic, but there are other weeds that look vaguely similar; see pachysandra sp. and parietaria sp.
AgreeLooks like it might be Pellitory, or "clustered white pellitory" Parietaria praetermissa
