Evergreen branches come from trees and shrubs that retain their leaves throughout the year. Unlike deciduous plants, which shed their leaves in autumn, evergreens maintain their foliage, providing a consistent green appearance. Common examples of evergreen trees include pine, fir, and spruce. These branches are often used in holiday decorations, wreaths, and garlands due to their vibrant color and pleasant scent. Additionally, evergreen branches play a crucial role in ecosystems, providing shelter and food for various wildlife, including birds and insects, throughout all seasons.
