Peppers

Peppers belong to the genus Capsicum, a distinctly American branch of the nightshade family. Their wild relatives range from Mexico and the Caribbean through Central America and much of South America. Rather than arising from one domestication event, today’s peppers represent several species shaped by Indigenous cultivators in different places.

Capsicum annuum—the species that includes bell peppers, jalapeños, poblanos, cayennes, and many other familiar forms—was domesticated in Mexico. Other cultivated species followed separate paths: C. chinense, which includes habanero-type peppers, is associated with tropical South America and the Caribbean; C. frutescens, C. baccatum, and C. pubescens also reflect long cultivation histories in Central or South America. Despite its name, C. chinense did not originate in China.

After sustained contact between the Americas and Europe began, peppers crossed the Atlantic and entered trade networks linking Europe, Africa, and Asia. They adapted especially well to warm climates and were rapidly incorporated into cuisines from India and China to Korea, Southeast Asia, Hungary, and the Mediterranean. Their global success sometimes obscures their exclusively American ancestry.

Peppers are now grown worldwide as fresh vegetables, dried spices, sauces, and specialty chiles. China, India, Mexico, Spain, and Türkiye are major producers, while California and New Mexico are important commercial growing regions in the United States. Modern peppers range from heatless bells to intensely pungent cultivars, but all trace their deeper history to the Americas.
