Carex perdentata, commonly known as Sand Sedge, is an evergreen perennial grass native to sandy prairies, open woodlands, and dunes in the south-central United States, particularly in Oklahoma and Texas. It typically grows to a height of 1 foot (0.3 meters) and can spread to about 3 feet (0.9 meters). This sedge forms dense clumps of fine-textured, narrow leaves that provide a unique texture in the landscape. It is not known for showy flowers, but its seed heads can add visual interest in the late summer and fall.

Sand Sedge is valued for its adaptability to poor, sandy soils and its drought tolerance, making it an excellent choice for xeriscaping and naturalistic plantings. It is often used in erosion control on slopes, as a ground cover in dry gardens, and in restoration projects where its native habitat is being recreated. Carex perdentata thrives in full sun to part shade and prefers well-drained soils. It is relatively low-maintenance, requiring minimal supplemental watering once established. While generally free of serious pests and diseases, it can suffer in overly wet conditions.CC BY-SA 4.0
