Introduced from Spain, the wild Sour Orange is found near streams in secluded, wooded areas of Florida and the Bahamas. The essential oils from the fruit of the Sour Orange are used in perfumes, as flavoring for liqueurs and also as a solvent. The fruit and leaves are said to make a lather and in earlier times were used for making soap. This variety of citrus is used as rootstock in groves of sweet orange and the fruit is also used in the production of orange marmalade.
