Oranges are green, not orange when grown in a tropical climate!


An orange is not a naturally occurring fruit , but rather a crossbreed of the tangerine and the pomelo, which is a fruit also known as the Chinese grapefruit. The first oranges were created in southeast Asia, where they would have been green, rather than orange.

The reason why oranges are green in a tropical climate is because the weather rarely gets cold. Because of the lack of cool weather, the chlorophyll remains in the skin of the orange, keeping it green. When an orange is exposed to cool weather while still on the branch it turns to orange. And orange that is left on the tree can change between green and orange several times depending on the weather.

This change of colors also means it’s impossible to tell if an orange is ripe. Fortunately for us, you don’t have to pay attention to if an orange is ripe. It remains ripe for a long time, even if left on the branch until the next season. The reason all of our oranges are orange in the store is because oranges are generally grown in subtropical areas, which means that they are exposed to cold weather. Oranges were able to give their name to the color because, most oranges are actually orange and not green.
