Citrus paradisi (Grapefruit)

The grapefruit is not very popular in Colombia where is it called toronja and cultivated below 8,500 feet. Even in the major supermarkets of Colombia you will see fruit sold that would not pass visual quality inspection in the U.S. as in the photo above. The grapefruits from the U.S. are of better taste.
