Sweetgrass (Hierochloë odorata) is more than a pretty grass, it’s a plant with deep roots in both ecology and culture. Its soft, arching leaves release a warm vanilla-like fragrance, especially when dried or crushed, making it a garden favorite for sensory richness. Sweetgrass spreads slowly by underground rhizomes, creating graceful mats that stay green through the seasons and produce subtle seedheads in late spring to early summer.
Beyond its beauty, Sweetgrass holds deep cultural significance for many Indigenous communities, where it has been traditionally used in ceremonies, for weaving, and as a sacred, aromatic plant.
Sweetgrass thrives in moist soils and sunny or lightly shaded areas, where it plays well with others. Pair it with moisture-loving natives like Rocky Mountain iris, native columbine (Rocky Mountain, Western, Oil Shale, Utah), Golden Currant or Woods Rose for a textured, pollinator-friendly border.
Whether grown for its cultural heritage, fragrance, or ground-hugging beauty, Sweetgrass adds a quiet yet profound presence to any thoughtful landscape.
