Native to North America, cranberries were eaten raw by aboriginal peoples before the Europeans arrived. The natives also boiled them, sweetened with maple syrup, and added them to pemmican, the dried food made of meat and berries.
Cranberries were the first fruit of the New World to be available commercially in Europe, beginning in the 1700's when "Cape Cod bell cranberries" were sold in London, England.
The fruit was first grown commercially in Canada on the East coast and in Newfoundland. Later, large plantings were started in British Columbia.
