💧 Water: Keep soil consistently moist; tolerates wet sites

🌱 Soil: Moist to wet, well-drained loam

❄️ Hardiness: Zones 3–9

🌼 Best Use: Wet gardens, naturalized areas, braiding, incense, cultural plantings

Key Rule: Sweet grass needs moisture. Dry soil reduces growth and fragrance.

Sweet grass is a fragrant, spreading perennial grass known for its warm, vanilla-like scent, created by naturally occurring coumarins in the leaves. When dried, the fragrance deepens, making this plant especially valued for traditional braiding, incense, and ceremonial use.

For many Indigenous communities across North America, sweet grass is considered a sacred plant and is traditionally braided and used in prayer, ceremony, and purification practices. Its cultural importance has been widely shared through works such as Braiding Sweetgrass, which highlights respectful harvesting and reciprocal relationships with plants.

We grow sweet grass with intention and care, honoring its cultural significance as well as its role in craft and landscape use. Our plants are cultivated thoughtfully, without chemical shortcuts, and with respect for both the plant and the traditions connected to it.

In the garden, sweet grass forms soft, arching clumps and spreads steadily by underground rhizomes. It thrives in moist to wet soils and is best suited for naturalized areas, rain gardens, and sites where spreading is welcome or can be managed.

Basic guidelines we encourage:

• Harvest only a portion of each clump
