Baloskion tetraphyllum, commonly known as Tassel Rope-Rush, is an evergreen perennial grass native to the wetlands, heathlands, and moist open forests of Eastern Australia and Tasmania. It typically grows to a height and width of 2 feet (0.6 meters), forming dense tussocks of fine-textured, green to dark green foliage. The plant is notable for its tassel-like inflorescences that appear in summer, adding a unique texture to garden settings. The flowers are not particularly showy but are interesting upon close inspection.

Tassel Rope-Rush is valued for its ability to thrive in wet conditions and is often used in water gardens, bog gardens, and as a pond margin plant. It is also suitable for mass planting as a ground cover in moist areas of the landscape. This species prefers consistently moist soils and can tolerate a range of light conditions from full sun to full shade. While it is adaptable to various soil types, it performs best in soils with poor to moderate drainage. In cultivation, it is relatively low maintenance, requiring only occasional trimming to remove old foliage.CC BY-SA 4.0
