A friend gave me some mint, and didn't mention what type it is. How can I tell if it's spearmint, peppermint, apple mint, lemon mint, or some other variety?
I googled some pictures, but quite frankly, all the pictures look very similar -- four leaves growing from the center which a textured leaf and a rich, green colour.
If it helps, I see what appears to be a purplish stolon making it's way across the surface of the soil (my soil is clay so I have this planted in maybe 3-4" deep soil right now).
(Close-up of leaves and flower. I picked alternatingly, so the plant originally has groups of four leaves.)
