The yellow nutsedge ( Cyperus esculentus ) is a tuber, a root vegetable, which is also called yellow nutsedge, ground acorn, ground almond or ground hazelnut, which is native to southern Europe and North Africa (it grows spontaneously in Corsica and Provence). The plant is a perennial by its tubers (in mild climates) but it is grown as an annual.

Hermaphrodite flowers with red spikelets can appear from August to November but it is quite rare outside the Mediterranean climate. However, the flowering shows the family resemblance with the false papyrus of our houses.

Small brown tubers clump together at the roots, at the base of the stems and these are the ones that are eaten: they are the size of a hazelnut, are a little elongated and scaly, as if wrinkled. Their taste is reminiscent of almond, hazelnut and peanut at the same time: they are eaten raw or cooked. Attention, the tiger nut is very rich in fat besides the Italians draw a table oil from it!
