    A Brief History of Blackberries

    It's tough to say where blackberries originated as they grow wild in Asia, Europe, North America and South America.

    And, not surprisingly, each region claims it as their own.

    The Greeks and the Romans are known to have used blackberries for medicine and Native Americans used them as food, medicine, twine, and dye.

    Documentation exists that blackberries were used in Britain in the late 17th century to make wine, cordials, jams, pies and other desserts, and the fruit became firmly entrenched in the pioneer cuisine of North America.


    Blackberries grow well on both the East and West Coasts of the United States, but the Pacific regions from Canada down to Mexico, are the main producers with Mexico leading worldwide production and Oregon harvesting 40 million pounds annually.
