Frontier Bilberry, in either berry or leaf form, is commonly known as huckleberry in the United States and is a European variety of blueberry. These fruits have a wide variety of uses and have a mildly acidic flavor. They may be eaten as dessert, steeped in tea or used as a garnish for tarts. Bilberries, or Vaccinium myrtillus, have rich blue-red pigments responsible for their unmistakable color.
