Granny Smith apples originated in Australia in 1868 when Maria Ann (Granny) Smith found a seedling growing by a creek on her property. This was the same place where she would toss French crab apples grown in Tasmania. The seedling bore light green colored apples that Granny Smith propagated. She found the new apple to be great for both cooking and snacking.
Washington apple growers began growing this apple commercially in the late 1960s. Today, Granny Smith is one of the most well-known apple varieties around, known for its bright green color and tart flavor.
