Originating from Central and South America pre-Columbus-around 1492 when Christopher Columbus documented Capsicum annuum-green peppers spread globally, revolutionizing diets. By 1920, U.S. cultivation hit 10,000 acres, per USDA archives. Today, in May 2026, global production exceeds 36 million tons annually, with green varieties prized for longevity and nutrition over riper colors.
