Cyperus rotundus is a perennial plant, that may reach a height of up to 40 cm. The names nut grass and nut sedge are derived from its tubers, that somewhat resemble nuts, although botanically they have nothing to do with nuts.

Cyperus rotundus (coco-grass, purple nut sedge, red nut sedge) is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia. The word cyperus derives from the Greek "???????" (kuperos) and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek ku-pa-ro, written in Linear b syllabic script. More
