Crops originating from Peru

Tropaeolum tuberosum (mashua, see below for other names) is a species of flowering plant in the family Tropaeolaceae, grown in the Andes, particularly in Peru and Bolivia, and to a lesser extent in Ecuador as well as in some areas of Colombia, for its edible tubers, which are eaten cooked or roasted as a vegetable. It is a minor food source, especially for native Amerindian populations. Mashua is a herbaceous perennial climber growing to 2–4 m (7–13 ft) in height. It is related to garden nasturtiums, and is occasionally cultivated as an ornamental for its brightly coloured tubular flowers. The leaves are peltate, roundly five-lobed with a petiole that twines weakly but is not truly a tendril. The root is tuberous.

Quinoa (Chenopodium quinoa; from Quechua kinwa or kinuwa) is a flowering plant in the amaranth family. It is a herbaceous annual plant grown as a crop primarily for its edible seeds; the seeds are high in protein, dietary fiber, B vitamins and dietary minerals especially potassium and magnesium in amounts greater than in many grains. Quinoa is not a grass but rather a pseudocereal botanically related to spinach and amaranth (Amaranthus spp.), and originated in the Andean region of northwestern South America. It was first used to feed livestock 5,200–7,000 years ago, and for human consumption 3,000–4,000 years ago in the Lake Titicaca basin of Peru and Bolivia.

Coca is any of the four cultivated plants in the family Erythroxylaceae, native to western South America. Coca is known worldwide for its psychoactive alkaloid, cocaine.

Lupinus mutabilis is a species of lupin grown in the Andes, mainly for its edible bean. Vernacular names include tarwi (in Quechua II, pronounced tarhui), chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, and pearl lupin. Its nutrient-rich seeds are high in protein, as well as a good source for cooking oil. However, their bitter taste has made L. mutabilis relatively unknown outside the Andes, though modern technology makes removing the bitter alkaloids easier. Like other species of lupin beans, it is expanding in use as a plant-based protein source.

Chili peppers, also spelled chile or chilli (from Classical Nahuatl chīlli ), are varieties of berry-fruit plants from the genus Capsicum, which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and the related capsaicinoids give chili peppers their intensity when ingested or applied topically. Chili peppers exhibit a range of heat and flavors. This diversity is the reason behind the availability of different types of chili powder, each offering its own taste and heat level.

Theobroma cacao (cacao tree or cocoa tree) is a small (6–12 m (20–39 ft) tall) evergreen tree in the Malvaceae family. Its seeds - cocoa beans - are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Although the tree is native to the tropics of the Americas, the largest producer of cocoa beans in 2022 was Ivory Coast. The plant's leaves are alternate, entire, unlobed, 10–50 cm (4–20 in) long and 5–10 cm (2–4 in) broad.

The potato is a starchy tuberous vegetable native to the Americas that is consumed as a staple food in many parts of the world. Potatoes are underground tubers of the plant Solanum tuberosum, a perennial in the nightshade family Solanaceae.

The cocoa bean, also known as cocoa or cacao, is the dried and fully fermented seed of Theobroma cacao, the cacao tree, from which cocoa solids (a mixture of nonfat substances) and cocoa butter (the fat) can be extracted. Cacao trees are native to the Amazon rainforest. They are the basis of chocolate and Mesoamerican foods including tejate, an indigenous Mexican drink.

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

Solanum quitoense, known as naranjilla ("little orange") in Ecuador, Costa Rica, and Panama and as lulo (from Quechua) in Colombia, is a tropical perennial plant from northwestern South America. The specific name for this species of nightshade means "from Quito."
