Carex willdenowii, commonly known as Willdenow’s Sedge, is a deciduous perennial grass native to a variety of habitats including moist to dry woodlands, meadows, and along stream banks in the Eastern and Southern United States. It typically grows to a height of 1 foot (0.3 meters) and can spread to a width of 3 feet (0.9 meters). This sedge forms dense clumps of fine-textured, grass-like leaves and produces inconspicuous greenish-brown flowers in late spring to early summer, which are not particularly showy but add a subtle texture to the landscape.

Willdenow’s Sedge is valued for its adaptability and is often used in rain gardens, naturalized areas, and as a ground cover in shaded sites. It is appreciated for its ease of maintenance and ability to thrive in a range of soil conditions, from moist to somewhat dry. In cultivation, it prefers partial to full shade, consistent moisture, and well-drained soils. While it is not known for aggressive roots or serious disease problems, it can self-seed and spread in optimal conditions, which should be monitored to prevent unwanted naturalization.CC BY-SA 4.0
