Nutgrass is a perennial sedge that spreads by underground tubers and rhizomes and is widely regarded as one of the worst weeds of farms and gardens. It grows easily in most soils and is best controlled by removing tubers rather than just cutting the top growth.

About

Cyperus rotundus (coco-grass, Java grass, nut grass, purple nut sedge or purple nutsedge, red nut sedge, Khmer kravanh chruk) 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 κύπερος, kyperos, and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek 𐀓𐀞𐀫, ku-pa-ro, written in Linear B syllabic script.

Where it grows

It prefers dry conditions, but will tolerate moist soils, and often grows in wastelands and in crop fields.

Uses

C. rotundus has many beneficial uses. It is a staple carbohydrate in tropical regions for modern hunter-gatherers and is a famine food in some agrarian cultures.
