Capsicum annuum
Capsicum annuum is a species of the plant genus "Capsicum" native to southern North America, the Caribbean, and northern South America. This species is the most common and extensively cultivated of the five domesticated capsicums. The species encompasses a wide variety of shapes and sizes of peppers, both mild and hot, such as bell peppers, jalapeños, New Mexico chile, and cayenne peppers. Cultivars descended from the wild American bird pepper are still found in warmer regions of the Americas. In the past, some woody forms of this species have been called "C. frutescens", but the features that were  used to distinguish those forms appear in many populations of "C. annuum" and are not consistently recognizable features in "C. frutescens" species. Characteristics. Although the species name "annuum" means “annual” (from the Latin "annus" "year"), the plant is not an annual but is frost tender. In the absence of winter frosts it can survive several seasons and grow into a large, shrubby perennial herb. The single flowers are an off-white (sometimes purplish) color while the stem is densely branched and up to tall. The fruits are peppers that may be green, yellow, orange or red when ripe. While the  species can tolerate most frost-free climates, "C. annuum" is especially productive in warm and dry climates. Pollination. While generally self-pollinating, insect visitation is known to increase the fruit size and speed of ripening, as well as to ensure symmetrical development. Pepper flowers have nectaries at the base of the corolla, which helps to attract pollinators. The anthers do not release pollen except via buzz pollination, such as provided by bumble bees. Uses. Culinary. The species is a source of popular sweet peppers and hot chiles with numerous varieties cultivated all around the world, and is the source of  popular spices such as cayenne, chile, and paprika powders. Common naming in English falls generally in line with the flavor and size of the variant. Larger, sweeter variants are called "capsicums" in Australia and New Zealand, "peppers" in the United Kingdom, and "bell peppers" in the United States. The smaller, hotter varieties are called chiles, chilies, chillies, chile, or chili peppers, or in parts of the US, "peppers". Capsinoid chemicals provide the distinctive tastes in "C. annuum" variants. In particular, capsaicin creates a burning sensation ("hotness"), which in extreme cases can last for several hours after ingestion. A measurement called  the Scoville scale has been created to describe the hotness of peppers and other foods. Traditional medicine. Hot peppers are used in traditional medicine as well as food in Africa. English botanist John Lindley described "C. annuum" in his 1838 "Flora Medica" thus: In Ayurveda, "C. annuum" is classified as follows: Ornamental. Some cultivars grown specifically for their aesthetic value include the U.S. National Arboretum's 'Black Pearl' and the 'Bolivian Rainbow'. Ornamental varieties tend to have unusually colored fruit and foliage with colors such as black and purple being notable. All are edible, and most (like 'Royal Black') are  hot. Host plant. The potato tuber moth ("Phthorimaea operculella") is an oligophagous insect that prefers to feed on plants of the family Solanaceae such as pepper plants. Female "P. operculella" use the leaves to lay their eggs and the hatched larvae will eat away at the mesophyll of the leaf.
