Pennyroyal Seeds

A charming, low-growing member of the mint family that has been cultivated for centuries for its aromatic foliage, ornamental beauty, and traditional uses. Forming dense mats of fragrant green leaves topped with attractive lavender-purple flowers, Pennyroyal is a favorite for herb gardens, pollinator plantings, pathways, rock gardens, and container displays.

The small leaves release a strong minty fragrance when touched or brushed, making Pennyroyal a pleasant addition to patios, walkways, and outdoor living spaces. Its compact growth habit and colorful blooms create an attractive groundcover effect while providing season-long interest in the garden.

Historically, Pennyroyal was widely grown in cottage gardens and monastery gardens throughout Europe. The aromatic foliage has long been used in sachets, potpourris, fragrant garden plantings, and traditional herbal collections. Today, gardeners often grow Pennyroyal primarily for its ornamental value, pleasant fragrance, and pollinator appeal.

During summer, the plants become covered with clusters of lavender to lilac-colored flowers that attract bees, butterflies, and beneficial insects. The flowers provide valuable nectar while adding beauty to herb gardens and mixed perennial plantings.
