Carex tenera, commonly known as Quill Sedge, is a perennial herbaceous plant native to moist meadows, marshes, and the edges of freshwater habitats in the northern United States and Canada. It is a sedge that thrives in wetland areas and is an important component of wet meadow communities. Quill Sedge typically grows to a height of 10-60 cm (4-24 inches) and has a clumping growth form. The plant features narrow, grass-like leaves and produces delicate, inconspicuous greenish-brown flowers in the late spring to early summer. The flowers are not particularly showy, but they do provide a subtle texture to the landscape.

Quill Sedge is valued for its ability to stabilize soil and filter water in wetland restoration projects. It is also used in rain gardens and naturalized areas where its low maintenance and ability to thrive in moist conditions are beneficial. In cultivation, it prefers full sun to part shade and requires consistently moist to wet soil conditions. It is not drought-tolerant and should not be allowed to dry out. While it is generally free from serious pests and diseases, it can suffer from root rot if planted in poorly drained soils. Quill Sedge is not known for being invasive and typically does not pose problems when grown outside its native range.CC BY-SA 4.0
