The World’s Most Widely Used Culinary Mint
Spearmint (Mentha spicata) is the mint behind most of the world’s culinary applications — the mint in mint sauce, in Middle Eastern tabbouleh and fattoush, in Indian chutneys, in Vietnamese fresh rolls, in British garden peas, and in the classic mojito. Unlike peppermint, which contains 40–55% menthol and delivers a sharp, intensely cooling bite, spearmint’s primary flavour compound is carvone — a gentler, rounder, sweeter mint flavour that complements food rather than overwhelming it. It’s the mint most cooks reach for by default, and for good reason: it works with an extraordinary range of flavours, from roasted lamb to fresh fruit to chocolate.
As a perennial, spearmint returns reliably each spring and spreads vigorously by underground runners. The standard solution is to grow it in a container, or to plant it in-ground inside a buried nursery pot with the bottom removed, which stops lateral spread while letting the roots access ground moisture. A single contained plant will still produce more fresh mint than most households can use through the growing season.

🇺🇸 US: Zones 4–9 as a perennial. Best in cool to moderate climates; flavour quality declines in sustained heat above 35°C (95°F). Grows year-round in mild Pacific Coast climates.
Best for: Kitchen herb gardens, container growing, tea gardens, companion planting near brassicas.
🌱 How to Grow Spearmint from Seed
Spearmint germinates best from seed on the surface — sow on moist seed-starting mix and press gently without covering, as mint seeds need light to germinate. Start indoors 8–10 weeks before last frost at 18–21°C (65–70°F). Germination takes 10–15 days and can be uneven. Transplant outdoors after last frost, 30–45cm (12–18 inches) apart, in partial to full sun with consistently moist, fertile soil.
Once established, spearmint needs very little care beyond regular harvesting and occasional watering in dry spells. It tolerates partial shade better than most culinary herbs. Harvest by cutting stems back by one-third; this encourages dense regrowth and delays flowering. For the most flavourful leaves, harvest just before flower buds open — essential oil concentration peaks at this stage.
🍹 In the Kitchen and the Glass
Fresh spearmint leaves are at their best used raw or added at the very end of cooking — prolonged heat destroys the volatile oils that carry the flavour. Classic applications include mint sauce for lamb (fresh leaves, white wine vinegar, a pinch of sugar), tabbouleh and fattoush salads, raita and mint chutney, Vietnamese-style fresh herb platters, and the mojito or mint julep. Fresh spearmint tea — a small handful of leaves steeped in just-boiled water for 5 minutes — is one of the simplest and most refreshing herbal teas, with a naturally sweet flavour that needs no sweetener.
