Sweetgrass (Hierochloë odorata) is a perennial grass native to temperate regions of North America, Europe, and Asia. It grows in moist prairies, floodplains, meadows, and open woodlands, forming dense clumps of slender, ribbon-like leaves that can reach up to three feet in length. The leaves are bright green, flexible, and highly aromatic, releasing a sweet, vanilla-like fragrance when crushed or dried.

The plant spreads slowly via rhizomes, stabilizing soil in natural habitats and preventing erosion along wet meadows and stream margins. Sweetgrass produces inconspicuous flowers in early summer, but it is the fragrant foliage that is most valued. Traditionally, the aromatic leaves are harvested for weaving, ceremonial braids, and medicinal preparations. Its combination of ecological resilience, fragrant leaves, and cultural significance makes sweetgrass a unique and treasured species for both herbal and ceremonial uses.
