Erdmandel

Chufa, also known as Tiger Nut or Earth Almond (Cyperus esculentus), is a cosmopolitan sedge in the family Cyperaceae valued for the edible, starchy tubers produced on its underground stolons. Originating in Africa, it was cultivated by ancient Egyptians and has spread to virtually all inhabited continents, thriving in warm to temperate regions with sufficient moisture. In Spain, chufa is commercially grown in Valencia for the production of horchata de chufa, a traditional sweet, milky non-dairy beverage made from soaked and ground tubers. The plant grows 20–90 cm tall with triangular stems characteristic of sedges, producing dense, grass-like foliage and small umbrella-shaped floral clusters. The pea-sized tubers are high in starch, sugars, fat, and dietary fiber. While valued as a food crop in some regions, Cyperus esculentus is considered an invasive weed in many agricultural contexts, particularly in maize, soybean, and sugar cane fields worldwide, where its deeply buried tubers make eradication difficult. The species is listed as Not Evaluated by the IUCN. Its global distribution and weedy habits make population-level threats essentially irrelevant in the conventional conservation sense.
