Summary

Schoenoplectus tabernaemontani, commonly known as Softstem Bulrush, is a deciduous, flowering perennial grass native to wetlands, including marshes, swamps, and riparian areas across temperate and tropical regions worldwide. It can grow to a height of 1–3 meters (33–100 inches) with numerous narrow, erect stems emerging from an extensive rhizome system. The inflorescence is a panicle of spikelets on long, thin branches that may spread, arch, or droop, with spikelets varying in color from brown to greenish. This species is particularly noted for its adaptability to fluctuating water levels and its role in water purification by trapping sediments and absorbing nutrients.

Softstem Bulrush is valued for its ecological benefits, such as providing habitat for wildlife and stabilizing soil in wetland areas. It is also used for ornamental purposes in water gardens and landscaping, with the ’Zebrinus’ cultivar being especially popular for its striking horizontal white or yellowish stripes. The plant is edible, with new shoots and young roots consumed raw or cooked, while older roots can be processed into flour. It thrives in full sun and requires high amounts of water, tolerating a range of soil drainage conditions from fast to slow. While it is easy to maintain, care should be taken as it can be potentially invasive outside its native range, and its aggressive growth may require management in garden settings.CC BY-SA 4.0
