Cyperus pseudovegetus, commonly known as the False Nutsedge, is a perennial herbaceous plant native to freshwater marshes, wet meadows, and the edges of ponds and streams in the southeastern United States, ranging from Texas to the Atlantic Ocean. It was first described by botanist Ernst Gottlieb von Steudel in 1854. This sedge typically grows to a height of 10-35 inches (25-90 cm) and forms dense clumps with triangular stems and grass-like leaves. The inflorescences are umbrella-like clusters of small, greenish-brown spikelets that appear in the summer and are not particularly showy.

False Nutsedge is valued for its ability to stabilize soil and filter water in wetland restoration projects. It is also used in rain gardens and as a ground cover in moist areas of the landscape. This sedge prefers full sun to part shade and requires consistently moist to wet soil conditions. It is not drought-tolerant and may require additional watering during dry periods. While generally low-maintenance, it can become invasive in ideal conditions, spreading rapidly by rhizomes. Gardeners should be aware of its potential to spread when considering it for their landscapes.CC BY-SA 4.0
