Solanum candidum

Solanum candidum is a species of evergreen shrub native to South America and occasionally grown for its edible fruit.

Undomesticated and very rare in cultivation, it is known as fuzzyfruit nightshade, [1] naranjilla silvestre or chichilegua. The fruit somewhat resembles the related cocona ( Solanum sessiliflorum ), and Solanum candidum will apparently hybridize with a number of close relatives, including cocona, naranjilla , and pseudolulo . One notable difference is the extremely hirsute fruits, which – unlike most of its relatives – do not detach easily upon full ripening, which is a hindrance to eating the ripe fruit. Nonetheless, S. candidum is a close relative of other nightshades cultivated for their edible fruit, including the tomato (S. lycopersicum), the naranjilla (S. quitoense) and the eggplant (S. melongena). Its relatively strong resistance to pests and disease (in comparison with its more appetizing relatives) has drawn some agricultural interest.

Scientifically, S. candidum is of additional interest, as it appears to be the closest relative and a possible ancestor to Asian members of the same botanical clade, notably Solanum lasiocarpum, which is native to India, but is cultivated for its naranjilla-like fruits, and will likewise readily hybridize with S. candidum.

Distribution and habitat

Solanum candidum is presumed to be native to the temperate Andean regions of Colombia, Peru and Chile. Like the cocona, naranjilla, and Indian nightshade, S. candidium can bear fruit within 1 or 2 years from seed. A short-lived perennial, fruit production requires a rather long growing season, which limits its agricultural potential in more temperate climates. Like the naranjilla and cocona, S. candidum is best adapted to subtropical cloud forest climates, where frost is unknown, but extreme heat is likewise very rare or unknown. The fruits are round berries, covered in a persistent fur even when ripe, to 2 cm in size, which ripen to yellow or red. Ripe fruits are less juicy than more commonly cultivated relatives, though the flavor is reportedly appealing.

Like most edible nightshades, the S. candidum is attractive to pests such as aphids, white flies, beetles, and spider mites, all of which can destroy naranjillas and coconas quickly. S. candidum reportedly has a slightly higher resistance to those pests.

Physalis peruviana, a plant species of the genus Physalis in the nightshade family Solanaceae, has its origin in Peru. The plant and its fruit are commonly called Cape gooseberry, goldenberry, and physalis, among numerous regional names. The history of Physalis cultivation in South America can be traced to the Inca. It has been cultivated in England since the late 18th century, and in South Africa in the Cape of Good Hope since at least the start of the 19th century. Widely introduced in the 20th century, P. peruviana is cultivated or grows wild across the world in temperate and tropical regions.

Solanum quitoense, known as Naranjilla in Ecuador and Panama and as Lulo in Colombia, is a tropical perennial plant from northwestern South America. The specific name for this species of nightshade means "from Quito."

<i>Pouteria campechiana</i> Species of plant

Pouteria campechiana is an evergreen tree native to, and cultivated in, southern Mexico, Belize, Guatemala, and El Salvador. It is cultivated in other countries, such as Costa Rica, Brazil, the United States, the Dominican Republic, Australia, Cambodia, Vietnam, Indonesia, India, Sri Lanka, Nigeria, and the Philippines. The edible part of the tree is its fruit, which is colloquially known as an egg fruit.

<i>Solanum sessiliflorum</i> species of plant

Solanum sessiliflorum, the cocona, is a tropical shrub of the family Solanaceae. The cocona plant has sturdy branches and huge, serrate and hairy leaves. Cocona closely resembles a number of close relatives, including naranjilla and pseudolulo. It can be distinguished from those plants by its lack of spines. It will hybridize with those and other close relatives. Cocona also lacks the characteristic purple coloring usually seen in the naranjilla. Its flowers resemble large potato flowers, with light green petals. Cocona is harvested in parts of South America around the Amazon rainforest such as Purús Province in eastern Peru.

<i>Pouteria caimito</i> Species of plant

Pouteria caimito, the abiu, is a tropical fruit tree originated in the Amazonian region of South America. It grows to an average of 33 feet (10 m) high, and can grow as high as 116 feet (35 m) under good conditions. Its fruits' shape varies from round to oval, pointed at the distal end. When ripe, it has smooth, bright yellow skin and has one to four ovate seeds. The inside of the fruit is translucent and white. It has a creamy and jelly-like texture and its taste is similar to the sapodilla — a sweet caramel custard. The abiu tree is part of the family Sapotaceae and is very similar in appearance to the canistel.

Tomato Edible berry of the tomato plant, originating in South America

The tomato is the edible, often red, berry of the plant Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America and Central America. The Nahuatl word tomatl gave rise to the Spanish word tomate, from which the English word tomato derived. Its domestication and use as a cultivated food may have originated with the indigenous peoples of Mexico. The Aztecs used tomatoes in their cooking at the time of the Spanish conquest of the Aztec Empire, and after the Spanish encountered the tomato for the first time after their contact with the Aztecs, they brought the plant to Europe. From there, the tomato was introduced to other parts of the European-colonized world during the 16th century.
