''Solanum quitoense'', known as naranjilla ((:naɾaŋˈxiʎa), "little orange") in Ecuador and Panama and as lulo (, from Quechua) in Colombia, is a subtropical perennial plant from northwestern South America. The specific name for this species of nightshade means "from Quito."〔Lamarck, Jean Baptiste Antoine Pierre de Monnet de. Tableau Encyclopédique et Methodique ... Botanique 2: 16. 1794.〕 The naranjilla plant is attractive, with large elongated heart- or oval-shaped leaves up to 45 cm in length. The leaves and stems of the plant are covered in short purple hairs. Naranjilla are delicate plants and must be protected from strong winds and direct sunlight. They grow best in partial shade. 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. ==Classification== Within the genus ''Solanum'', ''S. quitoense'' is a part of the subgenus Leptostemonum. Within this clade, ''S. quitoense'' belongs to the section Lasiocarpa. Other species within Lasiocarpa include: ''S. candidum'', ''S. hyporhodium'', ''S. lasiocarpum'', ''S. felinum'', ''S. psudolulo'', ''S. repandum'' and ''S. vestissimum''.〔 (2005): (''Solanum quitoense'' ). Version of December 2005. Retrieved 2008-SEP-25.〕 Other plants bear morphological similarity to ''S. quitoense'', but they may or may not be closely related. Some of these plants are: ''S. hirtum'', ''S. myiacanthum'', ''S. pectinatum'', ''S. sessiliflorum'' and, ''S. verrogeneum''. Many of these plants, related or not, can be confused with ''S. quitoense''. Furthermore, ''Solanum quitoenses physical traits vary from plant to plant, making identification challenging: at least three varietals (with spines, without spines, or a third variety known as ''baquicha,'' which features red-ripening fruits and smooth leaves) are known to occur. One characteristic that is unique to ''S. quitoense'' is the ring of green flesh within the ripe fruit.〔 The only related fruit to have green flesh is a cultivated variant of ''S. lasiocarpum''. The new growth of this plant is densely covered in protective trichomes. Coloration in the plant's trichomes around the new growth and flowers varies from purple to white. Identification can be difficult for this reason. Image:stalk 1.jpg|New leaf. File:stalk 1.jpg Image:stalk 2.jpg|Bud. File:stalk 2.jpg Image:stalk 3.jpg|Bud and baby leaf.
