C. annuum

Floridata et al provide the following facts about this species:

  • Capsicum annuum (“annual”) is by far the most important pepper species everywhere except South America. It is the most extensively cultivated throughout the world, and because it cross-pollinates so easily there are probably thousands of varieties in existence.
  • C. annuum probably originated in Central America and Mexico.
  • The flowers are usually solitary, and usually creamy white with no spots.
  • C. annuum used to be divided into two categories: sweet (or mild) peppers, and hot chili peppers. However, modern plant breeding has removed that distinction as hot bell varieties and sweet Jalapeños have now been cultivated.
