Common Christmas tree varietals include the Douglas fir, the Canadian balsam, the Noble fir, and the Fraser fir. Tom Foley, the proprietor of a popular Christmas tree lot in Brooklyn, New York, recommends that shoppers seek out a Fraser fir if possible. He prefers Frasers for a number of reasons, namely because the varietal boasts approximately 30 branches and gives off an especially piney scent.
