About Pennyroyal
Mentha pulegium, commonly known as pennyroyal, is an aromatic perennial herb from the mint family, characterized by its small oval leaves and purple flower spikes. It forms a dense, low-growing mat, ideal for ground cover in rock gardens, between stepping stones, or as a trailing plant. Its distinctive menthol and camphor-like scent is notable, though it should be handled with caution due to its toxicity if ingested in large quantities.
Native range
Europe and Western Asia
Care tips
Pennyroyal thrives in full sun to partial shade and requires regular watering to keep the soil consistently moist but not waterlogged. It adapts to a wide range of soils, preferring well-drained, slightly acidic to neutral types. It's crucial to note its invasive nature; planting in containers or with underground barriers is recommended to control its spread. Avoid internal consumption, as it is toxic in high doses.
