Seaside Arrowgrass
Softstem Bulrush

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.

Softstem Bulrush is a native perennial sedge that forms dense colonies of tall, upright stems. Thriving in saturated soils and shallow water, it spreads vigorously by rhizomes, creating large colonies that stabilize shorelines, control erosion, and strengthen wetland ecosystems.
Dense stands of Softstem Bulrush create shelter and nesting sites for birds, while also supporting aquatic invertebrates and the larvae of numerous insects. It is also an important food source. Many wetland birds, especially ducks, feed on the seeds, while muskrats feed on the foliage and rhizomes. Well-suited for ecological restoration, waterside & riparian plantings, erosion control, and habitat enhancement projects.
