Capsicum annuum, bell, sweet, or chili pepper—with cultivated varieties including bell, sweet, chili, and paprika peppers—is a perennial herbaceous plants in the Solanaceae (nightshade family), which originated in Central and South America and the Caribbean and was domesticated over 5,000 years ago. Peppers from C. annuum have been developed into numerous varieties that are now cultivated around the world for sweet and hot varieties of green and red bell peppers and chili peppers, that are one of the world’s most widely used spices, with dried forms including paprika, chili powder, and cayenne.
Although annuum (Latin: yearly) should be an annual plant, this species is perennial. Capsicum annuum is the most widely cultivated chilli in the world, both commercial and private. Because this species crosses so easily, there are thousands of different varieties. The Jalapeño is also one of them.
