Cyperus esculentus Linnaeus, Perennial yellow flatsedge
Cyperus esculentus is sparse in Renfrew County. It is found in disturbed sandy soils and especially abundant and weedy around Petawawa building lots during construction. The latin word 'esculentus' means 'edible' and refers to the tubers (Figure 5). In various parts of the world, some varieties of Cyperus esculentus (known as Chufa) are cultivated for their tubers - the tubers are generally known as Tiger Nuts.
