Carex sparganioides, commonly known as Bur-reed Sedge or Loose-headed Bracted Sedge, is a perennial herb that thrives in the understory of deciduous, mixed, and occasionally coniferous forests, as well as along forest streams and in moist woodland clearings in the eastern and central United States and eastern Canada. It typically grows to a height of 1-3 feet (30-90 cm) with a similar spread. This sedge is characterized by its grass-like leaves and inconspicuous greenish-brown flowers that appear in late spring to early summer. While the flowers are not showy, they add a subtle texture to the woodland garden. The plant forms dense clumps and can spread slowly by rhizomes, making it effective for soil stabilization, particularly on shaded slopes.

Bur-reed Sedge is valued for its ability to thrive in shaded conditions and its contribution to the biodiversity of woodland ecosystems. It is often used in naturalistic plantings, rain gardens, and as a ground cover in shaded areas. It prefers moist, well-drained soils rich in organic matter and can tolerate a range of light conditions from full shade to partial sun. While generally low-maintenance, it may require additional water during prolonged dry spells. There are no major disease or pest issues associated with this plant, but it is important to avoid overly dry or sunny locations, which can stress the plant.CC BY-SA 4.0
