Pennyroyal (Mentha pulegium)

Pennyroyal (Mentha pulegium) is a fragrant, low-growing perennial herb valued for its aromatic foliage, spreading habit, and clusters of soft lilac-purple flowers that bloom from mid to late summer. The small, oval green leaves release a refreshing mint-like fragrance when crushed, making this plant a popular choice for herb gardens, cottage gardens, and naturalistic landscapes. Its vigorous growth quickly forms a dense groundcover, helping to suppress weeds and soften garden edges.

Thriving in moist, well-drained soils and full sun to partial shade, Pennyroyal is easy to grow and highly adaptable. Due to its spreading nature, it is best planted where it has room to expand or contained in pots or raised beds to control its growth. The flowers attract bees and other beneficial pollinators, adding ecological value to the garden. Please note: Pennyroyal contains naturally occurring oils that are toxic if ingested by humans or pets and should be grown for ornamental or aromatic purposes only.
