Scientific Name: Marrubium vulgare

Uses: Since ancient Roman times, horehound has been used as an expectorant to treat coughs, colds and other respiratory ailments, as well as a digestive aid. Today, horehound is what gives many cough candies and syrups their distinctive flavor. The leaves and stems can be dried and kept year-round to make your own teas for respiratory and digestive support.

Hardiness: USDA Zone 4.

Growing Tips: Horehound grows wild throughout most of the world. You can grow it at home from either seed or plant divisions. Horehound spreads vigorously, so make sure you plant it somewhere with lots of room, or plant it in a pot to keep it contained. Trimming off the flowers before they set seed will also prevent its spread.
