Osmorhiza claytonii, commonly known as Clayton’s sweetroot or woolly sweet cicely, is a perennial herb native to the rich, deciduous forests of Eastern North America, particularly thriving on wooded slopes and in the understory where the soil is moist and fertile. It typically grows to a height of up to 35 inches and features large, compound, deeply divided leaves that give it a delicate, feathery appearance. In late spring to early summer, it produces small, inconspicuous white flowers that bloom in clusters on umbels, which are attractive to small and medium-sized pollinators. The plant emits an anise-like aroma when any part is broken or crushed, which can be quite pleasant to humans.

Clayton’s sweetroot is valued for its aromatic properties and is sometimes used in native plant gardens or naturalized areas. It is relatively low-maintenance, preferring shaded conditions and moist, well-drained soil. While not typically used for ornamental purposes due to its subtle flowers, it can be a beneficial addition to woodland gardens or naturalized areas, providing ecological support for pollinators. It is also of interest for its historical use in traditional medicine. The seeds of Osmorhiza claytonii are adapted for dispersal by attaching to animals with their barbed structures. Gardeners should be aware that in ideal conditions, it may self-seed and spread within the garden.CC BY-SA 4.0
