What is Capsicum annuum?
Capsicum annuum is a flowering plant in the nightshade family (Solanaceae) that is cultivated for its peppers. It is the most economically important species in the Capsicum genus, with common forms including bell, poblano, cayenne, pimiento, jalapeño, serrano, and other chili peppers.
C. annuum is propagated from seed and is frost-tender, so seedlings are often started in greenhouses. It is heat- and drought-resistant and grows well in rich, well-drained soil, blooming in the summer and fruiting in the summer and early fall.
The species was first domesticated in present-day Mexico about 6,000–7,000 years ago and spread worldwide after Christopher Columbus took the seeds to Europe. The pods are harvested, dried, and ground to produce paprika, which is rich in vitamin C.

Where is Capsicum annuum usually grown?
Capsicum annuum is widely cultivated for its peppers and is the most economically important species in the Capsicum genus. It is grown worldwide for its pods, commonly known as chili peppers. While C. annuum is native to South America, the garden pepper was first domesticated in Mexico.
C. annuum is frost-tender and typically grown as an annual, though it can survive as a short-lived perennial in warmer climates. Seedlings are started in greenhouses and transplanted when six to eight weeks old, after the threat of frost has passed. The plant thrives in rich, well-drained soil, with undisturbed roots and full sun. It blooms in the summer and fruits in the summer and early fall.

What do the fruits of Capsicum annuum look and taste like?
Capsicum annuum is a plant with varied fruit qualities. The fruits, which are true berries, exhibit a wide array of shapes and sizes, from the large, roundish bell peppers to the long, thin cayenne peppers.
Depending on the cultivar, the color of these berries can be green, red, yellow, orange, or black, and they often change color as they ripen. Capsicum annuum includes both sweet peppers and many pungent, strong-flavored types. The spiciness, or heat, of chili peppers is measured using the Scoville scale, ranging from 0 SHU (Scoville Heat Units) for a bell pepper to over 2.5 million SHU for the hottest varieties.

How are sweet and hot peppers different within Capsicum annuum?
Capsicum annuum is a plant species with thousands of varieties and cultivars producing both sweet and hot peppers. The level of pungency, or "heat," in hot peppers comes from capsaicin, with higher concentrations resulting in spicier peppers.
The Scoville scale measures this heat in Scoville Heat Units (SHU), ranging from 0 SHU in sweet bell peppers to over 2.5 million SHU in the hottest chili peppers. C. annuum includes both sweet peppers and many pungent varieties.

What are some uses of Capsicum annuum in cooking and medicine?
Capsicum annuum is a flowering plant with thousands of varieties, including bell, poblano, cayenne, pimiento, jalapeño, and serrano peppers. The fruits of Capsicum annuum are integral to cuisines worldwide and can be eaten raw, cooked, pickled, roasted, or dehydrated. Pungent chilies can be used as condiments or spices.
Pepper extracts are used in pharmaceutical products for conditions like arthritis and athlete’s foot. Cayenne peppers are also used in traditional medicine and pharmaceutical preparations for pain relief and other maladies. The fruits contain phytochemicals, including vitamins C and A, flavonoids, anthocyanins, carotenoids, and capsaicinoids. Paprika, a spice derived from C. annuum, is richer in vitamin C than citrus fruits.

Capsicum annuum, flowering plant of the nightshade family (Solanaceae), widely cultivated for the hot or mild peppers of its thousands of varieties and cultivars. Capsicum annuum is the most economically important of the species in the Capsicum genus. Its common forms include bell, poblano, cayenne, pimiento (including those used to make paprika), jalapeño, serrano, and various other chili peppers. The fruits of this species are integral ingredients in the cuisines of many countries worldwide. The plant is also grown as an ornamental or as a source of medicine.
Peppers can be eaten raw, cooked, pickled, roasted, or dehydrated. Pungent chilies can be used as condiments or spices for seasoning. Some peppers are also used as colouring in some foods. Pepper extracts are used in pharmaceutical products for such conditions as arthritis and athlete’s foot. The fruits contain many phytochemicals, including vitamin C, vitamin A, flavonoids, anthocyanins, and carotenoids, as well as capsaicinoids, which are spicy components of hot peppers.
History
Archaeological and genetic evidence indicates that the wild ancestors of C. annuum evolved in northern South America. Like other peppers, the species was spread by birds before it attracted human attention. Birds lack the sense receptors for capsaicinoids and are thus unaffected by a pepper’s spiciness; the seeds pass unharmed through birds’ digestive systems and are excreted in new places.

The plant was first domesticated by Indigenous peoples in present-day Mexico approximately 6,000–7,000 years ago. Chilies were an important food to many Indigenous populations, including the Aztecs. Returning from one of his voyages to the New World, Christopher Columbus took the seeds to Europe, and the species quickly spread across the continent and to Asia and Africa.
Physical description
The plant is an herb or small shrub that grows to a height of 0.3–1.2 metres (1–4 feet) and a width of 15–30 cm (6–12 inches). Its glossy leaves are roughly oval in shape with smooth margins and can reach up to 7.5 cm (3 inches) in length. The leaves of some cultivars turn dark purple or black as the plant grows.
The star- or bell-shaped flowers have 4–5 petals and are white, greenish, or purple or lavender in colour. The fruits are true berries and come in many shapes and sizes. For example, bell peppers are large, roundish, and furrowed, whereas cayenne peppers are long and thin. Depending on the cultivar, the fruits may be green, red, yellow, orange, or black, and many change colour as they mature. Given that the myriad of forms cross-pollinate easily, varieties and cultivars are often difficult to quantify and are usually classified by characteristics of the fruits, such as size, shape, colour, flavour, and pungency.
Cultivation
The many varieties and cultivars of C. annuum are propagated from seed. The species is frost-tender, and seedlings are often started in greenhouses and transplanted outdoors when they are six to eight weeks old, if the threat of frost has passed. The plant can survive as a short-lived perennial in warm climates but is frequently grown as an annual.

The species is heat- and drought-resistant, and the pungency of the fruits of some cultivars make the plants resistant to damage by deer and other animals. The plant grows well in rich well-drained soil. It does best in full sun and when its roots are left undisturbed. The plants typically bloom in the summer and fruit in the summer and early fall.
Capsicum annuum is affected by stem and root rot, fungal and bacterial leaf spot, mosaic virus, and wilt. The plants may suffer damage from insects, including whiteflies, aphids, pepper maggots, cutworms, and Colorado potato beetles. The species is a host plant for the potato tuber moth.
