Native Americans used to drink field mint tea as a remedy for colds, and it’s still used today for teas and flavorings for food. It’s an unusual-looking mint plant, with a square stem that grows from 6 to 18 inches tall with tufts of flowers puffing out around the stem every few inches. As with other types of mint, you can pick mature field mint leaves first thing in the morning for the best flavor. Enjoy them fresh chopped in iced tea, sprinkled on a salad or mixed into a variety of dishes. Dry the leaves for long term storage.
