I extracted some honey last year that smelled distinctly minty, and had a lovely spearmint like component to its odor.  It was gathered by one of my colonies of "Urban Bees"  in Clinton Township Michigan  (A suburb of Detroit.)  during late june or early july.  (Before the purple loosestrife came into blossom.)
After talking to a number of people, most thought it was probably linden or basswood honey.  Thre are quite a few linden trees planted in subdivisions within a mile or two of this hive, so it is a possibility, tho there are few such trees within 4-6 blocks of this hive.
