Wheat Sedge
Seaside Arrowgrass

Wheat Sedge is a native perennial sedge commonly found in wetlands, ditches, and along shorelines. It thrives in saturated soils, spreading by rhizomes to form large colonies that stabilize both soils and shorelines. This makes it valuable for wetland and riparian plantings.

Its distinctive, wheat-like seed spikes add seasonal character while providing food for waterfowl, and its dense clumps supply cover and nesting habitat for birds and small animals. Together, these traits make Wheat Sedge an important species for enhancing biodiversity and supporting healthy wetland ecosystems.

Seaside Arrowgrass is a native perennial commonly found in wetlands, salt marshes, and moist meadows. It is especially suitable for difficult growing sites. Its dense root system helps stabilize soil, while also providing food, cover, and habitat for small animals within the wetland community.

Seaside Arrowgrass is suitable for shoreline stabilization, wetland restoration, and naturalization projects.
