Woolgrass
Baltic Rush

Woolgrass is a native perennial sedge that forms dense clumps in wetlands, ditches, and along shorelines. Its ability to thrive in saturated soils and shallow water, combined with its spreading growth habit, makes it especially valuable for waterside & riparian plantings, erosion control, ecological restoration, and naturalization projects.
The distinctive spikelets are covered in brown woolly bristles, which is where it gets the name Woolgrass. It produces seeds that are eaten by waterfowl and small mammals, while its dense stems offer cover and nesting habitat. It grows most actively in spring and fall, slowing or going dormant in the summer heat.

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.
