This sedge exhibits narrow, grass-like leaves and triangular stems, typically reaching up to 3 feet (about 90 cm) in height. The inflorescences consist of umbrella-like clusters of small, greenish flowers that bloom in summer and fall. The plant's fibrous root system is well-adapted to saturated soils found in its preferred habitats.
