Horehound
Medicinal Herb
Horehound is a hardy perennial herb from the Lamiaceae family that has been treasured for centuries for its intensely bittersweet, minty character. Native to Mediterranean regions, this silvery-green plant produces delicate white blooms and grows to a compact 12-24 inches tall, thriving in zones 4-8 with minimal fussing. Ready to harvest within 70-79 days, horehound serves double duty as both a functional kitchen herb and an ornamental garden addition, particularly valued for teas, syrups, and traditional herbal candies.

Highlights
Silvery-green foliage and small white flowers give horehound subtle charm in the garden, but the real appeal lies in its distinctive bittersweet, minty flavor that transforms simple syrups and teas into something memorable. This heirloom perennial shrugs off frost, deer, and poor soil with equal indifference, asking only for full sun and well-draining earth. Once established, it demands almost nothing: minimal water, no fussing, just reliable harvests year after year from a plant that feels more like a friend than a chore.
Common Uses
Horehound shines in herbal teas, where its distinctive bittersweet, minty character creates a warming infusion with a slightly licorice undertone. The leaves and flowering tops are traditionally simmered into syrups for sore throats and persistent coughs, and dried horehound has long been the secret ingredient in old-fashioned herbal candies and lozenges. Fresh or dried, it also brings complexity to herbal blends and medicinal preparations where its intense flavor profile stands up to blending with other potent herbs.

Care Instructions
Start Indoors
Start horehound seeds indoors 6-8 weeks before your last spring frost. Sow seeds 0.25 inches deep in well-draining seed-starting mix and keep the soil consistently moist (not waterlogged) at temperatures between 50-70°F. Germination typically occurs within 2-3 weeks. Once seedlings develop true leaves and reach 2-3 inches tall, begin hardening off by exposing them gradually to outdoor conditions over 7-10 days before transplanting.
Transplant Outdoors
Transplant horehound seedlings outdoors after your last frost date when soil has warmed and hardened-off plants show vigorous growth. Space plants 18 inches apart with 24 inches between rows, allowing plenty of room for air circulation. Horehound is frost-hardy and tolerates cool soil, so you can transplant once nighttime temperatures consistently stay above 40°F.
Direct Sow
You can direct sow horehound seeds outdoors after your last spring frost, pressing seeds 0.25 inches deep into well-draining soil. Keep soil consistently moist until seedlings are established, then thin to 18-inch spacing. Direct sowing takes longer to reach harvest than starting indoors but eliminates transplant shock.
Harvesting
Harvest horehound leaves and flowering tops once the plant is well-established, typically 70-79 days after sowing. Begin picking when the plant reaches 8-10 inches tall and has developed multiple sets of true leaves; regular harvesting actually encourages denser, more productive growth. For the most potent flavor and medicinal properties, harvest in the morning after dew dries but before the day's heat. Cut stems just above a leaf node to encourage branching, and continue harvesting throughout the season as new growth appears.
Pruning
Pinch back young horehound plants when they reach 6 inches tall to encourage branching and a bushier habit. Once established, light pruning after flowering promotes fuller growth and prevents the plant from becoming leggy. You can harvest leaves and flowering tops regularly throughout the growing season; this ongoing harvest naturally shapes the plant into a compact, productive form.

History & Origin
“Horehound carries the weight of Mediterranean tradition, valued for generations in folk herbalism and candy-making before modern gardeners rediscovered it. True Leaf Market catalogs it as an heirloom, open-pollinated cultivar, emphasizing its role in the lineage of preserved, non-GMO seeds that gardeners have saved and replanted for centuries. Its presence in traditional syrups and confections speaks to a heritage rooted in European home remedy-making, where the plant's singular flavor became indispensable to cough drops and tonics passed down through families.”
