How to Grow & Harvest Horehound


Horehound (Marrubium vulgare) is a European herb that has been used medicinally since antiquity. It's a perennial in the mint family. You can start your horehound plant from seeds or cuttings---early spring is the best time to get it going. It spreads rapidly in most climate zones. A tea from the fresh leaves and flowers is used for lung congestion of colds, flu, laryngitis or other bronchial ailments. Horehound's dried leaves and flowers add a nice scent, beauty and interest to dried arrangements and you also can store them to use as tea during the winter when your plant is dormant.

Step 1

Fill pots or flats with standard potting soil in fall or spring and then sprinkle the surface with water.

Step 2

Scatter horehound seeds on top of the damp soil and then press them gently into the soil with your palm. If you are using a rooted plant division, poke a hole large enough for the roots and then pat the soil down around its base.

Step 3

Transplant 1-inch seedlings into individual 3-inch pots using the same type of potting soil you used to start your seeds.

Step 4

Transplant your young plants to a sunny spot in your garden in spring when they are 3 to 4 inches tall.

Step 5

Dry horehound by collecting small bundles of the fresh plant and hanging them in a warm, dark, dry, well-ventilated place, such as your garage. Then store it in sealed jars you keep in a dark place.

Step 6

Make tea from either the fresh or dried plant: Place about 3 tablespoons of the chopped leaves and/or flowers into a teacup and then pour boiling water over it. Allow to steep for five minutes and then sweeten with sugar or honey to taste.
