bell pepper

Bell pepper is a cultivar group of the species Capsicum annuum. Colors of the fruit include red, yellow, green and orange. Bell peppers contain a recessive gene that prevents capsaicin from being produced, so they lack the spiciness that many other varieties of peppers have. Bell peppers are sometimes grouped with less pungent pepper varieties as "sweet peppers".
