A genuine water-quality workhorse, soft-stem bulrush is valued as much for filtering and purifying water as for its ornamental cylindrical stems - a proven choice for both large-scale wetland restoration and smaller water garden installations alike.
Species Overview
Schoenoplectus tabernaemontanii, commonly called soft-stem bulrush, is a tall, aquatic sedge native to wetlands across North America. Cylindrical, smooth stems support clusters of brownish flowers in summer, with the species thriving in full sun and shallow water or saturated soils where it forms dense colonies through its rhizome system.
Application
Wetland restoration - water filtration and purification
Water garden and pond-edge plantings
Erosion control on shallow-water and saturated sites
Habitat plantings for wetland birds and amphibians
