Capsicum annuum is the species of many sweet peppers and hot chili fruit, including the Bell Peppers. Some of the cultivars of this species are: aleppo, anaheim, ancho, cascabel pepper, cayenne, guajillo, Italian sweet pepper, jalapeno, mirasol, puya, serrano, tien tsin.
The Bell Pepper is native to the Americas from Mexico south to northern South America. It was only when the Americas were discovered were the seeds spread to Europe and Asia.
Have you ever wondered why pepper is a name that designates two biologically different plants. The black peppers come from the infloresence of a Piper vine. Bell Peppers come from a deadly nightshade. Black Peppers were already known to Europeans when Christopher Columbus brought back the first Capiscum to Europe. In fact, peppercorns were highly prized in Europe. The resulting name was really just a misrepresentation of the plant.
