Summary
Carex obnupta, commonly known as Slough Sedge, is an evergreen perennial grass native to wetlands, marshes, and riparian zones along the West Coast of North America, from California to British Columbia. It typically grows to a height of up to 1.2 meters, forming dense clumps from its spreading rhizomes. The plant features upright, sharply angled stems and narrow, grass-like leaves. The inflorescence consists of a cluster of flower spikes, each accompanied by a long leaflike bract, which are not particularly showy but are interesting texturally. Flowering occurs in late spring to early summer.
Slough Sedge 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 bank stabilizer due to its high water requirement and tolerance of standing water. This sedge prefers full sun to part shade and thrives in wet, poorly drained soils. While it is low-maintenance, it can spread aggressively if conditions are ideal, which should be considered when planting in smaller areas.CC BY-SA 4.0
