Summary
Cyperus schweinitzii, commonly known as Schweinitz’s Flatsedge, is a deciduous perennial herb, that is native to wet meadows, marshes, and along the edges of ponds and streams in the Central and Eastern United States. It typically grows to a height of 0.7-3 feet (0.2-0.9 meters) and a width of 0.5-1 feet (0.2-0.3 meters). This sedge has a clumping form with triangular stems and greenish-brown flower spikes that appear in late summer. While not particularly showy, the flowers provide texture in a garden setting.
Schweinitz’s Flatsedge is valued for its ability to thrive in wet conditions and is often used in rain gardens, wetland restoration projects, and for erosion control along waterways. It is low-maintenance and can be an attractive addition to naturalistic plantings. In cultivation, it prefers full sun to part shade and requires consistently moist to wet soil conditions. It is not drought-tolerant and will need additional water during dry periods. While generally pest-free, it can become invasive in some areas if conditions allow for unchecked growth.CC BY-SA 4.0
