    Grapefruit (once known as Citrus x paradisi, but now redefined as a synonym of Citrus x aurantium) is a cross between a pomelo and a sweet orange, both parents being of Asian or Indonesian origin.
    The hybrid fruit was documented in 1750 by a Welshman, Rev. Griffith Hughes, who described specimens from Barbados.

    It was brought to Florida by Count Odette Philippe in 1823 in what is now known as Safety Harbor.

    Grapefruit and grapefruit juice have the potential to interact with numerous drugs. Check with your doctor or pharmacist if you take medications.

    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.
