Mentha spicata
herbSpearmint is the common sweet mint, milder and less sharply cool than peppermint, with a clean, sweet flavor used in teas, sauces, salads, and drinks like mojitos and mint juleps. Like all mints it is a hardy perennial that spreads enthusiastically by runners and returns each spring, supplying fragrant leaves throughout the season.

Plant in full sun to part shade in moist, fertile soil, and contain spearmint in a buried pot or barriered bed, since its runners spread as aggressively as any mint and will take over a garden. Water for lush growth, shear the plants back a couple of times a season to keep them leafy and prevent flowering, and divide crowded clumps to keep the patch productive.

Space for airflow, avoid wetting the foliage, and remove infected stems
Keep soil moist and rinse foliage in hot, dry spells
Hose off colonies and encourage ladybugs and lacewings
Snip sprigs as needed all season, with the flavor strongest just before flowering, and frequent cutting keeps fresh leaves coming. Pick in the cool morning for the best aroma, and dry or freeze the leaves to preserve them, though spearmint is at its best used fresh.
Spearmint is eaten in small amounts but contributes vitamin A, antioxidants, and aromatic oils, and like other mints it has a traditional use for soothing digestion, with a gentler, sweeter flavor than peppermint.
