Blue Wood Sedge
Blue Wood Sedge is a clumping, cool-season sedge native to the southeastern and central U.S., prized for its lush, blue-green foliage that lights up shaded gardens and rain gardens alike. Reaching 8–12 inches tall, it forms well-behaved mounds that add soft texture to woodland understories, path edges, or as a groundcover under shrubs and trees. Its broad leaves offer a fresh alternative to finer-bladed sedges, with a striking hue that stands out in moist, low-light settings.
Thriving in partial to full shade, this sedge tolerates periodic flooding and heavy clay, making it ideal for poorly drained areas or shade rain gardens. It supports a range of wildlife, serving as a larval host for several skipper butterflies and providing shelter for native bees and beetles. Its tidy habit and adaptability make it a low-maintenance anchor in any shade planting.
