chufa sedge

Cyperus esculentus

''Cyperus esculentus'' is a crop of the sedge family widespread across much of the world. It is native to most of the Western Hemisphere as well as southern Europe, Africa, Madagascar, the Middle East and the Indian Subcontinent. It has become naturalized in many other regions, including Ukraine, China, Hawaii, Indochina, New Guinea, Java, New South Wales and various oceanic islands.

''Cyperus esculentus'' can be found wild, as a weed, or as a crop. There is evidence for its cultivation in Egypt since the sixth millennium BC, and for several centuries in Southern Europe. In Spain, ''C. esculentus'' is cultivated for its edible tubers, called earth almonds or tiger nuts, for the preparation of "horchata de chufa", a sweet, milk-like beverage. However, in most other countries, ''C. esculentus'' is considered a weed.
