Carex serratodens, commonly known as Sawtooth Sedge or Korean Sedge, is a perennial grass native to California. It exhibits a moderate growth rate, reaching heights of 1.5-2 feet (0.46-0.6 meters) and spreading 1-1.5 feet (0.3-0.5 meters) wide. The plant forms dense clumps of narrow, serrated foliage and produces green, inconspicuous flowers that bloom in the spring and summer, followed by small, brown fruiting bodies.

Sawtooth Sedge is valued for its ability to thrive in wet conditions and its use as a ground cover or edge planting in water gardens, rain gardens, and along pond margins. It is also suitable for erosion control due to its dense root system. This sedge prefers consistently moist soils but can tolerate periods of dryness once established. It is adaptable to full sun or part shade and grows well in medium draining loam or clay soils. While generally low-maintenance, it can be susceptible to rust and leaf spot diseases under certain conditions.CC BY-SA 4.0
