Summary

Osmorhiza occidentalis, commonly known as Western Sweet Cicely or Western Sweetroot, is a perennial herb that is native to the moist, shaded understory of montane and subalpine forests in western North America, including the Northwestern United States and California. It typically grows up to 3 feet tall and thrives in cool, damp environments often found at elevations between 3937-9843 feet. Western Sweet Cicely has a delicate appearance, with fern-like foliage and clusters of small, inconspicuous yellowish flowers that bloom in late spring to early summer. The plant’s roots have a sweet, anise-like fragrance and flavor.

Western Sweet Cicely is valued for its aromatic roots and foliage, which have been used by Native American groups for culinary and medicinal purposes, including as a flavoring agent and for digestive ailments. In cultivation, it prefers partial to full shade and well-draining, loamy soil. While it is not commonly found in the average garden, it can be used in naturalized woodland gardens, as a border in shady areas, or for restoration projects. It is relatively low-maintenance once established but may require additional water during dry periods. Potential problems include leaf miners and slugs, especially in overly moist conditions.CC BY-SA 4.0
