Commonly known as naranjilla in Ecuador, Costa Rica, and Panama, and lulo in Colombia, this tropical perennial plant originates from northwestern South America, particularly the Andean valleys near the equator​​​​. The fruit is known for its distinctive citrus flavor, often compared to a mix of rhubarb and lime, which is particularly popular in beverages and is an excellent tasty juice. However, the plant's fruits, akin to tomatoes, are fragile when ripe and thus are typically harvested before they fully ripen to prevent damage. The plant has been hybridized with other Solanum species, such as S. sessiliflorum, to improve resistance​​ to disease.
