Recognizable by the navel (belly button) at the bottom of the fruit, the original navel orange was discovered in Brazil at the turn of the century. One tree was started in Riverside, California. From this one tree came the California navel orange known throughout the world as the best eating orange available. We grow several varieties of navels at Deer Creek Heights Ranch including the original Washington navel.
So what is the purpose of the navel? It is a second orange.
