Beaked Sedge
Seaside Arrowgrass

Beaked Sedge is a native perennial wetland plant that forms dense clumps of tall, grass-like stems. It produces distinctive beaked seed heads that mature from late spring into summer. The plant provides food for waterfowl, muskrats, and other wildlife, while its dense growth offers cover for birds and small mammals. Its flowers and seed structures contribute to pollinator and invertebrate habitat in aquatic ecosystems.

Thriving in saturated soils and shallow water, Beaked Sedge is common in marshes, fens, and riparian zones. Its rhizomatous growth enables it to spread into large colonies that stabilize soils and support overall wetland health. Hardy and low-maintenance once established, it is well-suited to riparian plantings, naturalization, and ecological restoration projects.

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.
