Softstem Bulrush

Knotted Rush is a native perennial wetland plant found growing in marshes, swamps, wet meadows, and along shorelines. It spreads by underground rhizomes to form colonies, which can also help stabilize soils and shorelines.

Its upright, slender stems and small clusters of greenish-brown seed heads add structure to wetland plant communities. Knotted Rush is well-suited to wetland conservation, rain gardens, naturalization, and restoration projects. As a cool-season grower, it grows actively during spring and fall, when temperatures are cooler.

Softstem Bulrush is a native perennial sedge that forms dense colonies of tall, upright stems. Thriving in saturated soils and shallow water, it spreads vigorously by rhizomes, creating large colonies that stabilize shorelines, control erosion, and strengthen wetland ecosystems.

Dense stands of Softstem Bulrush create shelter and nesting sites for birds, while also supporting aquatic invertebrates and the larvae of numerous insects. It is also an important food source. Many wetland birds, especially ducks, feed on the seeds, while muskrats feed on the foliage and rhizomes. Well-suited for ecological restoration, waterside & riparian plantings, erosion control, and habitat enhancement projects.
