Grown in California, Arizona and Florida, the navel is an excellent eating orange. Its name originates from the fact that the blossom end resembles the human navel. This large fruit has a bright-orange skin that's thick and easy to peel. The pulp is sweet, flavorful and seedless. Available from late fall through late spring, the navel orange is sometimes called Washington, Riverside or Bahia navel. See also orange.
