Baltic Rush is a widespread native perennial rush that forms dense clumps of upright, cylindrical stems. Well adapted to saturated soils, it is common in wetlands, streambanks, and riparian zones, and is tolerant of both fresh and saline conditions. Hardy and low-maintenance, Baltic Rush contributes to soil stabilization and enhances wetland habitats.

It offers cover for small animals, nesting habitat for birds, and limited forage for livestock when young and tender. Its dense growth and rhizome networks add structural diversity that supports wetland ecosystems, making it well-suited for riparian planting, shoreline stabilization, wetland restoration, and reclamation projects.
