Northern Sweetgrass
Northern Sweetgrass is a fragrant, cool-season native grass valued as much for its cultural importance as its graceful beauty. Forming loose clumps of glossy green blades, it grows 1–2 feet tall and releases a sweet, vanilla-like aroma when crushed or dried, an effect attributed to the natural compound coumarin. In early summer, it sends up delicate, airy panicles that sway above the foliage, adding soft movement and a fine-textured accent to garden compositions.
Naturally found in moist prairies, open woods, and streambanks, Sweetgrass thrives in full sun to part shade and prefers moist, well-drained soils. It spreads gradually by shallow rhizomes to form low mats that suppress weeds, stabilize soil, and provide nesting material for birds and small mammals. This species is traditionally used by many Indigenous communities in ceremonies, braiding, and basketry; respected as a sacred plant symbolizing healing, connection, and peace.
Why Choose Northern Sweetgrass?
- Fragrant foliage and soft, waving flower spikes
- Provides cover and habitat for small wildlife
- Spreads gently to form attractive, soil-stabilizing mats
Plant in moist, sunny or partly shaded spots. Trim in early spring to encourage fresh growth. Divide every few years to rejuvenate older clumps and prevent thinning. Avoid planting in very dry soils unless irrigated occasionally.
- Prefers moist soil but is somewhat drought-tolerant once established.
- Cut back old foliage in early spring to make room for fresh, vigorous growth.
- Best in moist, rich soils but adapts to a range of conditions as long as drainage is good.
- Mulch lightly to retain moisture and suppress weeds.
- Divide clumps every few years in spring to rejuvenate growth and manage spread. Allow space for rhizomes to expand.
