Marrubium vulgare (Horehound)

Marrubium vulgare, commonly known as Horehound, is a hardy, clump-forming perennial herb known for its aromatic, gray-green, woolly leaves. The foliage is slightly crinkled, creating a textured, silvery appearance that contrasts beautifully with other plants. In summer, it produces small, tubular, white flowers arranged in whorls along upright stems. Horehound is traditionally valued for its medicinal properties and is often used in herbal remedies and teas.

Marrubium vulgare thrives in well-drained, poor to moderately fertile soils and is drought-tolerant once established, making it ideal for xeriscaping or rock gardens. It is deer-resistant and low-maintenance, requiring little more than occasional pruning to maintain its shape and remove spent flower stems. This versatile herb pairs well with other drought-tolerant plants like lavender, thyme, and sage, creating a harmonious, Mediterranean-style garden display. It is a great choice for herb gardens or as a border plant in sunny, dry areas.
