I don’t know what that big white plant is in the picture just above, but the pollinators were going absolutely nuts over it. They absolutely adored this entire garden, which they treated as an extensive snack highway.
Very impressive. And very cheerful!
Boneset (Eupatorium perfoliatum) perhaps? Being its a North American native plant it would not surprise me if it was a pollinator magnet.
