Growing Guide: Pennyroyal
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 6–9. In warmer climates, provide afternoon shade to prevent stress.
