Navel oranges are a popular variety of sweet oranges known for their seedless nature and easy-to-peel skin. They are typically larger than other orange varieties and have a distinctive navel-like formation at the blossom end, which is actually a small, undeveloped fruit. Navel oranges are primarily grown in warm climates, with California being one of the largest producers. These oranges are rich in vitamin C and are often enjoyed fresh or in juices. They are usually in season from November to April, making them a popular choice during the winter months. Their sweet flavor and juicy texture make them a favorite for snacking and adding to salads.
