black sedge
Carex nigra
Black sedge (Carex nigra) is an amazing addition to any garden. It features attractive black foliage and slender, graceful stems. The foliage is very dense, making it a great barrier against weeds and erosion. It produces an abundance of purple or pink flower spikes, adding a nice burst of color. This sedge prefers moist soils and is usually found in wetlands, riparian habitats, and along stream banks where it will form large dense clusters. It’s fairly low maintenance and can be allowed to spread naturally to create a beautiful groundcover. Thanks to its ability to tolerate wet conditions and its attractive foliage color, Black sedge is a wonderful addition to any garden.
