Sweetgrass

Botanical Identification

• Common Names: Sweetgrass, Seneca Grass, Holy Grass, Vanilla Grass

• Latin Name: Anthoxanthum nitens (formerly Hierochloe odorata)

• Known Habitat: This resilient perennial grass flourishes in the moist, rich soils of wet meadows, riverbanks, and marshy lowlands throughout the Great Lakes region and northern climates.

The Significance of Sweetgrass

For many American Indian communities, Sweetgrass is recognized as the sacred hair of Mother Earth. It is deeply revered for its sweet, lingering vanilla-like fragrance—a scent that actually grows stronger as the plant dries. In traditional teachings, a single strand of grass is weak and easily broken, but when woven together into a braid, it becomes incredibly strong, symbolizing the strength of community, mind, body, and spirit working in unison.

Holistic Uses

• Spiritual Cleansing: When burned, the sweet-smelling smoke is used in smudging ceremonies. While medicines like sage are often used to clear away negative energy, sweetgrass is traditionally burned afterward to attract positive energies, invite good spirits, and carry prayers upward.

• Crafting and Weaving: The strong, flexible leaves have long been harvested, dried, and carefully re-soaked to weave intricate baskets, bowls, and artistic items that retain their beautiful scent for years.

• Topical Preparations and Teas: Because of its high coumarin content—which provides its signature scent—the dried grass can be infused into natural oils and salves for a soothing, aromatic addition to human skincare, or steeped into a mild, fragrant tea.

Harvesting and Processing

Gathering Sweetgrass is a practice of patience, intention, and respect. It is typically harvested from mid-to-late summer. Culturally and ecologically, the stems are carefully cut near the base rather than pulled by the roots, ensuring the root system remains undisturbed so the plant can return the following year.

Once gathered from the wetlands, the long grasses are sorted, traditionally braided into tight strands while still pliable, and hung in a dry, well-ventilated area to cure slowly.

Correctly identifying sweetgrass (Anthoxanthum nitens) relies on a combination of distinctive physical characteristics and its signature aroma. The most defining feature of sweetgrass is its strong, vanilla-like scent, caused by a high coumarin content, which becomes even more pronounced as the plant dries. Visually, sweetgrass features long, slender leaves that are distinctly shiny and hairless on their undersides. Unlike many look-alike grasses that grow in isolated, densely packed tufts, sweetgrass spreads via creeping white or yellow underground rhizomes, and the base of its stems often displays a white or reddish-purple hue. During its early blooming period from spring to early summer, it produces loose, open panicles with bronze-colored spikelets, further distinguishing it from other meadow grasses that lack its unique sweet fragrance and creeping root system.
