Carex feta, commonly known as Green-sheathed Sedge or Greensheath Sedge, is a perennial herb native to wet meadows, marshes, and streambanks in the Pacific Northwest, including southwestern British Columbia, Washington, Oregon, and California. It typically grows 20 to 39 inches tall and features green-bladed leaves. The plant produces open inflorescences that are 1.2 to 3.1 inches long, with the fruit being green to pale gold and ovate, appearing from May to August. The flowers are not particularly showy, but the plant has a graceful, fountain-like form that adds texture to garden settings.

Green-sheathed Sedge is valued for its ability to thrive in wet conditions and is often used in rain gardens, riparian plantings, and as a naturalizing element in moist garden areas. It prefers full sun to part shade and requires consistently moist to wet soil conditions. While it is not known for significant pest or disease issues, it can spread in favorable conditions and may need to be managed to prevent unwanted naturalization. This sedge is similar to Carex fracta but can be distinguished by its smaller and more distinct spikelets.CC BY-SA 4.0
