That white Swamp Milkweed sure is nice! Do you think it is a natural variation or an escaped cultivar? (I've seen white cultivars for sale lately...but would be cool to have found a 'natural' version.)
Also the one you have labeled "Bonset" (assuming you had meant Eupitorium perferatum) is likely Tall Bonset/Tall Throughwort - Eupatorium altissimum as the leaves are not perforated. E. altissimum is quite rare in my neck of the woods so that would be a great find up here. ;P
