Vigorous, versatile, and INVASIVE. Always grow in containers. Spearmint (M. spicata) is standard culinary. Peppermint (M. x piperita) for teas. Vietnamese mint (Persicaria odorata) is NOT a true mint but fills a similar niche in warm climates. All true mints spread aggressively by underground runners.
