Summary

Hedeoma drummondii, commonly known as Drummond’s false pennyroyal, is a hairy perennial herb native to rocky slopes and grasslands in the southwestern United States and northern Mexico. It typically grows up to 18 inches tall and features linear to narrowly oval leaves that emit a strong mint scent when crushed. The plant produces light to deep lavender flowers from late spring to early fall, which are not only showy but also attract a variety of pollinators, including bees and butterflies.

Drummond’s false pennyroyal is valued for its aromatic foliage and delicate flowers, making it a suitable choice for rock gardens, herb gardens, and as a ground cover. It thrives in full sun to part shade and prefers well-drained soils. While it is drought-tolerant once established, it benefits from occasional watering during prolonged dry periods. In parts of Mexico, the flowers and leaves are harvested for their minty flavor and used in culinary applications. Gardeners should note that while it is generally easy to maintain, it can spread rapidly and may require control measures to prevent it from becoming invasive in some areas.CC BY-SA 4.0
