Like FATC1TY said, the tea option will give you a rough idea. The old rub-n-sniff test is always a good method to give you an idea of what type of aroma and flavor they hold. All of the wild ones I've found over the years have had the typical wild N. American notes. Kinda rank, pungent and what I pick up as B.O.. I think this may be the onion/garlic aroma that others describe. Good luck.
