The Ultimate Guide to Growing Mullein from Seeds

```

Answer: Cold stratify Mullein (Verbascum thapsus) seeds moist 4-6 weeks fridge, then surface sow post-frost in full sun poor well-drained alkaline soil, thinning to 12-18 inches; first-year rosettes precede 2-7 ft flowering spikes year two. Drought-tolerant biennial self-seeds prolifically (100,000-240,000/plant); harvest leaves anytime, flowers June-September. USDA zones 3-9 thrive; studies confirm decades-long seed viability promoting disturbed sites.Seed Guide – Sow True Seed Cultivation Notes – Homestead Culture Mullein Profile – OISO. "Direct sow outdoors fall for natural stratification or fridge 30-60 days moist before spring planting," advise seed specialists.

Mullein transforms poor soils into towering medicinal spikes supporting pollinators. Gardeners value its low care and traditional respiratory remedies from self-sustaining stands. Biennial cycle rewards patience with abundant harvests.

## Mullein Basics Verbascum thapsus biennial forms year-one basal rosettes of fuzzy gray-green leaves, sending 2-7 ft spikes of yellow flowers year two. Native Europe/Asia, naturalized widely; deep taproot aids poor/disturbed sites. Seeds viable decades. ## Seed Starting Steps ### Stratification - Moist medium fridge 4-6 weeks breaks dormancy. - Fall direct sow mimics winter for spring emergence. ### Sowing - Surface scatter—light needed; press gently. - Thin seedlings 12-18 inches; full sun alkaline pH 7+. ## Care Essentials - Drought-tolerant post-establishment; water rosettes sparingly. - No fertilizer; competes weeds via shading. - Deadhead spikes prevents excess seeding if desired. ## Harvesting Uses Leaves anytime year one for teas; flowers mid-spike June-September for oils. Pods yield 100k+ seeds; dry/store cool dark. Traditional expectorant; external poultices soothe skin. ## Safety Notes Who should avoid: Pregnant/nursing or liver patients consult doctors—may interact. Skin irritation possible; strain teas finely. Many use topically first. ## Common Mistakes - Deep burial blocks light—no germination. - Wet soil rots taproots—ensure drainage. - Rich feeding leggy non-bloomers. ## Conclusion Mullein builds resilient self-perpetuating medicinal patches effortlessly. Sow once, harvest repeatedly. Embrace its wild utility.
