Pennyroyal Seeds - Herbal Plant for Home Gardens

Pennyroyal, botanically known as Mentha pulegium (European pennyroyal) or Hedeoma pulegioides (American pennyroyal), is a low-growing aromatic herb valued for its spreading habit and small clustered flowers. It develops creeping stems with rounded leaves and produces tiny purple to lavender blooms during the growing season. This plant adapts well to temperate climates and performs best in full sun to partial shade with moist, well-drained soil. Pennyroyal is commonly used in herb gardens, borders, and ground cover planting, where it establishes readily from seeds and spreads under suitable conditions.
