Carex gynodynama, commonly known as Sedge, is a perennial herbaceous plant native to moist meadows, forest openings, and along streams in Western North America. It is particularly adapted to clay soils and areas with seasonal moisture. This sedge typically grows to a height of 1-2 feet (0.3-0.6 meters) and a width of 0.5-1 feet (0.2-0.3 meters). Its foliage is grass-like, with a fine texture and a deep green color. The inconspicuous green flowers bloom in the spring and summer, followed by seed heads that may provide interest in the garden.

Carex gynodynama is valued for its ability to thrive in challenging conditions, such as wet or damp areas where other plants might struggle. It is often used in rain gardens, as a ground cover in shady spots, and for erosion control on streambanks. This sedge is low-maintenance, requiring medium amounts of water and tolerating a range of soil types, though it prefers part shade to full shade and medium to slow-draining clay or loam soils. While generally disease-free, it can suffer from root rot if the soil is too waterlogged. It is not known to be invasive and is a good choice for naturalistic plantings and habitat restoration projects.CC BY-SA 4.0
