Ulluco

Ulluco is a vibrantly colored Andean tuber, second only to potato in Peruvian highland cultivation, prized for its waxy texture, mild earthy-sweet flavor, and striking yellow, pink, red, and spotted skin.

History & Origins

Ulluco was domesticated by pre-Columbian Andean peoples, likely by 5500 BCE, and archaeological finds in Peruvian tombs confirm its cultivation alongside potato and oca for thousands of years. Spanish chroniclers of the 16th century documented its central role in the diet of the Inca and their subjects, and the National Research Council later designated it one of the 'Lost Crops of the Incas' due to its neglected global potential.
