Cyperus rotundus, often known as nutgrass, is a globally distributed herbaceous plant from the sedge (Cyperaceae) family. Cyperus rotundus forms underground, tuberous rhizomes, which are responsible for the propagation and storage of nutrients. The above-ground parts consist of narrow, grass-like leaves and upright stems that can grow up to 60 cm high. The plant's small brown flowers are rather inconspicuous and appear in loose spikes on the upright stems.
