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.

Hardstem Bulrush is a tall, native perennial wetland plant that thrives in shallow water and saturated soils, often forming extensive stands in wetland and shoreline habitats. Well suited to riparian restoration, bank stabilization, shoreline protection, and naturalization projects, it spreads through underground rhizomes to form dense colonies.

Hardstem Bulrush’s tall growth provides valuable cover and nesting habitat for waterfowl, songbirds, and small mammals, while its late-summer seeds provide food for waterfowl and other birds.
