White Horehound (Marrubium vulgare) Organic Seeds – Woolly Gray-Green Perennial Herb, Classic Ingredient for Cough Drops, Candy & Herbal Tea

Minimum: 60+ Seeds

White Horehound — The Bitter Herb Behind the Classic Cough Drop

Before menthol lozenges lined pharmacy shelves, this woolly gray-green herb was the cough remedy people actually trusted. White horehound has flavored candy, tea, and folk medicine since Roman times, prized for a bitter, minty edge that cuts through congestion. Its felted, silvery leaves make it as much a texture plant as a medicinal one, soft enough that gardeners plant it just to touch it. This seed comes from growers who still treat it as a working herb, not a novelty.

Who Grows White Horehound?
The home candy maker wanting the real bittering agent for horehound drops.
The herbalist stocking a respiratory tea blend the traditional way.
The pollinator gardener who knows bees work its small white flowers hard.
The dry-garden gardener needing something tough that still looks intentional.
The homesteader keeping a working medicinal bed, not just ornamentals.

What This Classic Cough Herb Actually Is
Marrubium vulgare is a perennial mint-family herb native to Europe, North Africa, and Asia, now naturalized across North America. The plant forms a low, spreading clump of square, woolly stems and crinkled, felted gray-green leaves, giving it its common name, from a texture like soft white wool. It sends up spikes of small white flowers along the upper stems in its second year, favored by bees. The leaves and flowering tops carry marrubiin, a bitter compound behind both the herb's traditional use as a cough remedy and its flavor in old-fashioned horehound candy. It self-seeds aggressively and is considered weedy in parts of Australia and the western United States, so site it where spread is welcome. Not currently of conservation concern. Hardy in USDA zones 3 through 10.

In the Kitchen & Apothecary

• Horehound candy: Simmer leaves and flowering tops into a strong tea, then boil down with sugar for hard drops.
• Cough and cold tea: Steep dried leaves alone or with lemon and honey for a bitter, traditional tea.
• Bitters and tonics: Add to homemade digestive bitters for the sharp, minty bitterness herbalists prize.
• Pollinator planting: Let a patch flower fully in a border to draw bees through summer.
• Dried herb sachets: Bundle dried stems for a rustic, textural addition to dried arrangements.
• Tincture base: Use fresh or dried tops as the classic base for homemade horehound tincture.

Before You Close This Page
This is the real cough-drop herb, not a modern substitute. White horehound has flavored candy and cold remedies since antiquity, with a bitter, minty edge marrubiin gives it. The woolly gray-green foliage is as striking as it is medicinal. It thrives on neglect: poor soil, full sun, little water. Bees work the flowers hard once it blooms in year two. It self-seeds readily, so give it room or manage it. Zones 3 through 10, drought-tolerant, low-maintenance. Grow the herb that soothed sore throats before cough drops came in foil.
