This plant has LARGE leaves (hard to tell from the photo but some are probably 5" inches long by about 3 inches wide), has a definite (to several of us) chocolate scent when leaves are crushed, and is blooming with spikes of small, pink flowers. I would say it's a basil-type flower but could also be a mint structure. It doesn't smell particularly mint-like and the leaves are quite large -- the size of a good-sized coleus leaf. It was a volunteer that came in a pot of chives from a plant swap.

Any notion of what it is? Chocolate mint? Or the mythical (perhaps fitional?) chocolate basil?
