The Korean Fir (Abies koreana) is a small tree with purple cones that become brown as they mature in the summer. This evergreen has flattened needles 1/2 to 1″ long and that are green on top and have two white spots on the underside. Like other fir trees, the needles are attached to the branch by a base resembling a suction cup. The tree grows in a pyramidal shape and is used as a Christmas tree. The Korean fir was introduced to the West by Enrnest Wilson in 1917.
