Seaside Arrowgrass

Slimstem Reedgrass is a native perennial bunchgrass commonly found in damp meadows, wetlands, and along streams and lakeshores. It thrives in wet, nutrient-poor soils and shows some tolerance to saline conditions. Typically a bunchgrass, it can also spread by rhizomes to form colonies, making it well-suited for soil stabilization, riparian zone planting, and wetland restoration projects.

Slimstem Reedgrass provides valuable cover for small animals and birds, and its dense growth can even serve as nesting habitat for waterfowl in wetland areas. Its seeds offer forage for wildlife, while the tall stems and floral spikes add texture and visual interest to the landscape.

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.
