The U.S. Postal Service issued its first commemorative ???Forever??? stamp in 2010 with a Holiday Evergreens set of four. ?Pine cones and berries are shown from four different conifer (evergreen) trees ??C ponderosa pine, eastern red cedar, blue spruce, and balsam fir. ?Pine trees are frequently used for decoration in the holiday season months, a welcome splash of living greens during the cold, dreary months.
