White Horehound, Heirloom Herb Seeds

White Horehound, Heirloom Herb Seeds — The Traditional Cough Herb With Beautiful Silver Foliage

White Horehound (Marrubium vulgare) has earned its place in the herb garden through centuries of practical use — the traditional remedy for coughs and respiratory complaints that gave us horehound candy and cough drops. Mounds of silvery, woolly foliage grow 18 inches tall and somewhat broader, creating a beautiful, long-lasting display through most of the season. The leaves carry a pleasantly bitter, aromatic flavor that has been used in teas, lozenges, and syrups for generations. A hardy, drought-tolerant perennial that is beloved by bees and butterflies, and remarkably easy to grow once established.

Why Grow White Horehound?

• The traditional cough herb — centuries of use in teas, lozenges, and syrups
• Beautiful silver woolly foliage — ornamental mounds 18 inches tall, long-lasting through the season
• Hardy drought-tolerant perennial — thrives with minimal care once established
• Bee, butterfly, and hummingbird friendly — a valuable pollinator plant
• Pleasantly bitter aromatic flavor — excellent in herbal teas and preparations
• Open-pollinated heirloom — save seed year after year

Growing Notes

Surface sow indoors 8–10 weeks before last frost — seeds need light to germinate. Keep soil moist at 65–70°F. Transplant outdoors after frost danger has passed in full sun with well-draining, lean soil. Drought-tolerant once established — avoid overwatering. Trim back after flowering to maintain compact mound shape. Self-sows modestly once established.
