Cyperus esculentus (also called chufa sedge, nut grass, yellow nutsedge, tiger nut sedge, or earth almond) is a crop of the sedge family widespread across much of the world. It is found in most of the Eastern Hemisphere, including Southern Europe, Africa and Madagascar, as well as the Middle East and the Indian subcontinent.

This plant reproduces by tiny underground tubers called nutlets. These tubers are tough enough to withstand winters and will survive in the soil for over three years.
