Answer
Dear Marinar, thank you for posting more images. The capitula (i.e., flower heads) look very much like Centaurea X moncktonii, a hybrid between brown knapweed and black knapweed. This is a common hybrid in New England. The leaves are a little problematic, however, as this species usually does not have blades with the degree of lobing shown in your images (at least in my experience). Puzzling plants.
