Creek Sedge, Carex amphibola, is a robust perennial sedge that grows in compact mounds. The narrow leaves are shiny, upright and often semi-evergreen. In late spring green scaly flower spikes top the gracefully shaggy foliage. This is a sedge for a woodland or shade garden with moist or wet soil. Plants are indigenous to deciduous floodplain forests, mesic forests with acidic loamy soils, flatwoods, slopes above streams or creeks, seeps, lake shores and moist upland deciduous woodlands.

Creek Sedge is a vigorous clump forming sedge with a mounding or fountain like habit. The arching glossy leaves are semi-evergreen in warm climates and deciduous further north. Leaves are about a foot long and less than 1/8” wide. In late spring this sedge bears several elongated green flower clusters that are distributed along the culm. The lower spikes are female or pistillate and the terminal spike is male or staminate. Plants are 12-18” tall with an equal spread.

Creek Sedge thrives in shaded sites with deep moist soil or in good garden soil. Plants will tolerate sun but may need some irrigation during summer. This sedge will self-seed but since it is not an aggressive seeder this is usually not a problem.
