Plukenetia volubilis, commonly known as sacha inchi, sacha peanut, mountain peanut or Inca-peanut, is a perennial plant with somewhat hairy leaves, in the Euphorbiaceae. It is endemic to the Amazon Rainforest in Peru, where it has been cultivated by indigenous people for centuries, and will grow in warm climates up to altitudes of 1,700 meters (5,500 feet) as long as there continued availability of water and good drainage. It grows better in acidic soils and alluvial flats near rivers.
