    Hello there, I would like to confirm or not... Is this Common Boneset - Eupatorium perfoliatum? In my research I noted that the leaves are uniformly triangular. These leaves aren't. What do you think. Thank you so much. I am very glad to have found you!

    Answer

    Dear SueLB, good morning. I'm not sure where you are located, so my answer cannot be confident (location information is vital for plant identification). This looks like Pseudognaphalium obtusifolium (blunt-leaved rabbit-tobacco). It is a species with alternate leaves that are not fused to a leaf on the opposite side of the node (Eupatorium perfoliatum has opposite leaves that are fused to each other at the common node). Note also the coating gray, woolly hairs on the stems and underside of the leaves (not found in Eupatorium perfoliatum). I hope this helps.
