Solanum quitoense, known as naranjilla (Spanish pronunciation: [naɾaŋˈxiʎa], "little orange") in Ecuador and Panama and as lulo ([ˈlulo], from Quechua) in Colombia, is a subtropical perennial plant from northwestern South America. The specific name for this species of nightshade means "from Quito." The fruit has a citrus flavour, sometimes described as a combination of rhubarb and lime. The juice of the naranjilla is green and is often used as a juice or for a drink called lulada.
