Western Sweet Cicely (Osmorhiza occidentalis) is a shade-tolerant woodland perennial with anise-scented foliage and small white flower clusters. It prefers moist, humus-rich soil in dappled shade, making it ideal for woodland or shaded border plantings. Water regularly to keep the soil from drying out, and it will naturalize gracefully under trees and along stream banks.
