Every year since 1947, the people of Oslo, Norway have given a Christmas tree to the city of Westminster, England. The gift is an expression of good will and gratitude for Britain's help to Norway during World War II.
From the University of Illinois Extension:
- Christmas trees have been sold commercially in the United States since about 1850.
- Until fairly recently, all Christmas trees came from the forest.
- In 2002, Oregon, North Carolina, Michigan, Pennsylvania, Wisconsin, Washington, New York, and Virginia were the top Christmas tree producing states. Oregon was the leading producer of Christmas trees – 6.5 million in 2002.
- The best selling trees are Scotch pine, Douglas fir, Noble fir, Fraser fir, Virginia pine, balsam fir and white pine.
- More than 2,000 trees are usually planted per acre. On an average 1,000-1,500 of these trees will survive. In the North, maybe, 750 trees will remain. Almost all trees require shearing to attain the Christmas tree shape. At six to seven feet, trees are ready for harvest. It takes six to ten years of fighting heavy rain, wind, hail and drought to get a mature tree.
- In the United States, there are more than 21, 000 Christmas tree growers.
- In the United States, there are around a half billion Real Christmas Trees growing on U.S. farms.
- In the United States, there are more than 12,000 cut-your-own farms.
- In 1979, the National Christmas Tree was not lighted except for the top ornament. This was done in honor of the American hostages in Iran.
