Summary

Micromeria douglasii, commonly known as Yerba Buena, is an evergreen perennial herb or subshrub native to moist woodlands, streambanks, and coastal scrub in the Western USA, particularly California, and extending into British Columbia, Canada. It typically grows to a height of 0.3-0.7 feet (0.09-0.2 meters) and spreads 3-6 feet (0.9-1.8 meters) wide, forming a dense, aromatic ground cover. The leaves are small, rounded, and emit a pleasant spearmint-like fragrance when crushed. Yerba Buena produces tiny, tubular, pale lavender to white flowers in the spring and summer, which are not particularly showy but attract pollinators.

Yerba Buena is valued for its aromatic foliage and its use as a traditional medicinal herb by indigenous peoples. It is often used in gardens for ground cover, in rock gardens, or as a fragrant addition to herb gardens. This plant thrives in part shade to full sun, prefers moist, well-drained soils, and tolerates a range of soil types, including clay. It is drought-tolerant once established and requires low to medium amounts of water. While it is not known for serious pest or disease problems, it can become invasive outside its native range, so gardeners should be cautious about planting it in areas where it may spread uncontrollably.CC BY-SA 4.0
