Abies fraseri (Fraser Fir)

Abies fraseri (Fraser Fir) is an evergreen coniferous tree that grows to a height of 10 to 15 metres (30 to 50 feet). Fraser Fir has been used more times as the Blue Room Christmas tree (the official Christmas tree of the President of the United States's White House) than any other type of tree. The crown is conical, with straight branches that are either horizontal or inclined upward at 40° from the stem; while the tree is young, it is thick, but as it matures, it becomes more open. On young trees, the bark is thin, smooth, grayish brown, and has many resinous blisters, becoming fissured and scaly as the tree matures.
