Pennyroyal (Mentha pulegium)
Regular price $18.95Low-Growing Aromatic Mint with Intense Herbal Fragrance
Pennyroyal is a low-growing, spreading mint with small rounded leaves and soft purple flowers that bloom in mid to late summer. Unlike taller culinary mints, this species forms a creeping mat, making it excellent as a groundcover in herb gardens or containers. When crushed, the leaves release a strong, sharp, minty aroma with earthy undertonesāmuch more intense than common peppermint or spearmint. Its compact habit and fragrant foliage make it both ornamental and highly aromatic in the landscape.
Fast-growing and adaptable, Pennyroyal thrives in warm conditions and can quickly fill in spaces with its trailing stems. Its dense foliage also naturally suppresses weeds when planted as a living groundcover.
Cultural & Herbal Significance
Pennyroyal has a long history in European and Mediterranean herbal traditions, where it was valued for its aromatic qualities and use in traditional remedies. Historically, it was used in herbal teas, strewing herbs, and natural insect deterrents. In older folk traditions, pennyroyal was associated with purification and protection. Today it is most commonly grown for its fragrance, ornamental use, and as a natural garden companion plant.
Important note: Pennyroyal contains concentrated essential oils and should not be consumed in large quantities or used medicinally without professional guidance.

Growing Tips
(Also known as: Pennyroyal, European Pennyroyal, Mentha pulegium, Creeping Pennyroyal, Squaw Mint (historical name))
Plant in full sun to partial shade with well-drained soil. Pennyroyal prefers consistent moisture but can tolerate brief dry periods once established. Like other mints, it spreads by runners, so plant in containers or bordered beds if you want to control growth. Trim regularly to maintain shape and encourage fresh growth. Hardy in USDA Zones 6ā9. In warmer climates, provide afternoon shade to prevent stress.
