The Fraser fir is native to the Appalachian Mountains. It is a relatively small tree compared to other firs with a mature height between 30 and 50 feet. Its short, upturned needles and dense branching boost its value as a Christmas tree. There are twelve species of fir native to North America. Firs are characterized by needles that are flat or broadly oval in cross-section. The large cones sit upright on the branches and have numerous scales. The cones do not fall off the tree whole, but slowly disintegrate as the seeds are dispersed. Their most common habitat is mountainous regions, where they enjoy cool summers and good, rich soil.
