Dark-green bulrush (Scirpus atrovirens) is a rhizomatous perennial native plant, well-suited to moist prairies, bogs, stream banks, lake edges, marshes, and other wetland areas across Eastern and Central North America. This plant forms clumps of upright stems reaching up to 1.2 metres tall, topped with dark green spikelets that turn brown by mid-summer and remain attractive through fall. While it may be too vigorous for small gardens, dark-green bulrush is ideal for ecological restoration projects and for erosion control in wetland areas due to its strong roots and rhizomes.
Ecological Roles
Dark-green bulrush plays a vital role in wetland ecosystems. Its robust root and rhizome system stabilizes wet soils and prevents erosion, providing essential protection for riverbanks and lake shores. It also offers habitat and shelter for various aquatic animals and cover for birds. By fostering biodiversity and improving soil structure, this plant is invaluable in wetland restoration projects and contributes significantly to aquatic ecosystem resilience.
Dark-green bulrush seeds require cold stratification to ensure germination. See the cultivation notes below for more details.
