Boughs of evergreen refer to the branches of evergreen trees, which retain their green foliage throughout the year. Common types of evergreen trees include pine, fir, and spruce. These trees are often used in holiday decorations, symbolizing endurance and life, as they do not shed their leaves in winter. Evergreen boughs are popular in various cultural traditions, especially during the Christmas season. They are used to create wreaths, garlands, and centerpieces, adding a natural touch to festive decor. Additionally, evergreen boughs can be used in landscaping to provide year-round greenery in gardens and outdoor spaces.
