1. The fruit was named before the color. For hundreds of years in English, the color orange was just called "yellow-red" (geoluread)! People didn't start using "orange" as a color word until after the sweet citrus fruit was imported to Europe from Asia in the Middle Ages.

2. Navel oranges have a tiny twin orange hiding inside. Look at the bottom of a navel orange—that little button shape is actually a second, tiny undeveloped orange growing inside the main one!

3. Blood oranges get their deep red color from anti-aging pigments. Unlike standard orange fruit, blood oranges have dark crimson-colored flesh. They get this deep red hue from natural pigments called anthocyanins, which develop when the fruit ripens during chilly night temperatures!

4. Ripe oranges can turn green again. If ripe oranges stay on the tree during warm weather, they can absorb chlorophyll back into their peel and turn green again! This is called "regreening," and the fruit inside stays perfectly sweet and ready to eat.

5. Florida and Brazil are the orange juice superpowers. Brazil grows more oranges than any other nation on Earth, while Florida produces the majority of orange juice made in the United States, growing tens of millions of citrus trees every year!

6. Sweet oranges are a human-made hybrid. Oranges didn't originally grow wild in nature! Long ago in ancient Asia, farmers created the sweet orange by cross-breeding two wild citrus fruits: the mandarin and the pummelos (a large ancestor of the grapefruit).

7. One orange packs a whole day's supply of Vitamin C. Eating just one medium-sized orange provides over 100% of the recommended daily amount of Vitamin C, a vital nutrient that strengthens your immune system and helps body tissues heal.
