Carex harfordii, commonly known as Harford’s sedge, is a perennial herbaceous plant native to the understory of coastal coniferous forests and mixed evergreen forests in California, particularly in the Coast Ranges. It is adapted to moist, shaded conditions often found in riparian zones and forested wetlands. Harford’s sedge typically grows in dense clumps reaching 12 to 18 inches (30 to 45 centimeters) in height, with narrow, grass-like leaves that are evergreen in mild climates.

Harford’s sedge is valued for its ability to stabilize soil and provide habitat for wildlife. It is often used in restoration projects and naturalized plantings where its ecological benefits can be maximized. In cultivation, it prefers part shade to full shade and consistently moist soils with good drainage. It is relatively low maintenance, requiring minimal care once established. While not known for showy flowers, its fine-textured foliage adds a delicate, naturalistic element to shade gardens and woodland settings.CC BY-SA 4.0
