Osmorhiza claytonii, commonly known as Sweet Cicely, is a native perennial wildflower found in rich woodlands, forest edges, and shaded slopes throughout Illinois. It thrives in moist, well-drained, humus-rich soils and prefers partial to full shade, making it ideal for naturalized woodland gardens and understory plantings.
This plant typically grows 1 to 3 feet tall and features soft, hairy stems with compound, fern-like leaves that emit a pleasant anise-like scent when crushed. In late spring to early summer, it produces small clusters of white flowers arranged in delicate, flat-topped umbels. The flowers are followed by narrow, elongated seeds with hooked bristles that easily cling to fur or clothing.
For Illinois native plant enthusiasts, Osmorhiza claytonii is a subtle but valuable addition to shaded native plantings. It supports a variety of early-season pollinators, adds texture and fragrance to the woodland floor, and pairs well with companions such as Wild Ginger, Virginia Bluebells, and Woodland Phlox in rich, shaded environments.
