Fennel Microgreens: Nature’s Anise-Scented Superfood

Fennel microgreens, the young seedlings of Foeniculum vulgare, are a culinary and nutritional gem. Harvested 12–18 days after sowing, these feathery greens bring a sweet licorice-anise flavor and a powerhouse of antioxidants, vitamins, and bioactive compounds that far exceed mature fennel. Their delicate texture and vibrant aroma make them a favorite for chefs, home cooks, and health enthusiasts.

Nutritional Highlights

Per 100g serving, fennel microgreens offer:

• 31 calories, rich in vitamins and minerals including vitamin C (74.94 mg, twice mature fennel), potassium (414 mg), calcium, iron, vitamin A, and vitamin K.
• Phenolics (408.03 mg GAE)—the highest among tested microgreens—providing potent antioxidant protection.
• Essential oils including anethole, responsible for the signature sweet licorice flavor.
• Dietary fiber supports digestive health and cardiovascular function.

Health Benefits

• Powerful antioxidant and anti-inflammatory effects.
• Digestive support through carminative properties reducing bloating.

• Boosting cocktails with fresh herbal notes.
• Complementing Mediterranean and fruit-based dishes.

Growing Fennel Microgreens at Home

1. Use Florence or Sweet fennel seeds (~20g per 10×20 tray) in coconut coir or seed mix.
2. Sow evenly, cover with vermiculite or humidity dome, and apply 2–3 lbs weight for 3–5 days at ~75°F.
3. Provide 12–16 hours of grow light or bright indirect sun at 60–75°F post-germination.
4. Bottom-water daily, keeping medium moist.
5. Harvest at 12–18 days when true leaves appear, yielding ~142g per tray.
