The white spruce tree grows naturally in Eastern Canada and the northeastern United States.  One of the hardiest evergreens, it needs a cold climate to survive.  It thrives on a wide variety of soils, but grows more slowly when the soil is acid or wet.  Historically they are the "classic" Christmas tree because they are the most abundant in the wild and grow into the best shape naturally.  They have poorer needle retention than other varieties and give off a strong evergreen odor in a warm room.  They are known to be attracted to bright lights, happy children and fat little men in red suits.
