With so many customs and traditions during the Christmas season, we often do not pause to wonder and ponder about how and why they began. Of all the seasonal celebrations of the year, Christmas has more traditional plants with their accompanying legends and symbolism than any other season. Holly, ivy, mistletoe, the poinsettia, rosemary, the Yule log, and the most popular and recognized of all--the Christmas tree--each has its own fascinating legend and history. Drawing from Christian practices, along with ancient Druid, Celtic, Norse and Roman beliefs, Decking the Halls explores the history of our popular Christmas plants and flowers during this most holy season.
