Peppers are native to Mexico, Central America, and northern South America. Pepper seeds were imported to Spain in 1493, and from there spread to other European, African, and Asian countries.
Today, China is the world’s largest pepper producer, followed by Mexico and Indonesia.
Ideal growing conditions for bell peppers include warm soil, ideally 21 to 29 °C (70 to 84 °F), that is kept moist but not waterlogged.
Red bell peppers are simply ripened green peppers
although the Permagreen variety maintains its green color even when fully ripe. Green peppers are less sweet and slightly more bitter than yellow or orange peppers, with red bell peppers being the sweetest.
