Horehound (Marrubium Vulgare) - You can grow Horehound seeds and use the perennial herb plant in your own soothing teas, or if you are adventurous, in your own homemade candy.
Did you eat Horehound candy when you were a child? You may not have known it, but your parents were actually giving you "medicine"! Candy made from the herb Horehound was often given as a cough drop to sooth deep chest coughs.
Marrubium Vulgare Horehound can be established from herb seeds and harvested the first year. This woody perennial has hairy stems covered with 2-inch, toothed, downy, gray-green leaves. The leaves have a wooly crinkled appearance. Small, off-white hairy flowers are born in summer (often start out as lilac or pale lilac) on the 8 - 24 inch tall and wide plant. The flowers attract beneficial wasps and flies to the garden. It's a great companion plant for tomatoes and peppers as an added bonus.
Grow the Horehound herb plants in any well-drained soil in full sun. Keep cutting back for new flushes of growth and extended harvests. The leaves and flowers lose their flavor quickly, so snip them into smaller pieces to dry on screens. When dry, crumble and store in jars. Cut the flowers and harvest it heavily each season as this plant is a liberal self-sower, dropping its own Horehound seeds and spreading.
How To Grow Horehound Seeds: Sow the flower seeds indoors on sterile starting mix. Keep the Horehound seeds moist until germination. Once frost season has passed and 2 leaves have formed on the seedlings, they are ready to transplant into the garden in a sunny location. Do not over water the Horehound plant. It likes to dry out in-between waterings.
