"Evergreen" refers to plants, particularly trees and shrubs, that retain their leaves throughout the year, regardless of the season. Unlike deciduous trees, which shed their leaves in autumn, evergreen plants maintain their foliage, providing year-round greenery. Common examples include pine trees and fir trees, which are often associated with winter landscapes.
In a broader context, "evergreen" can also describe content or ideas that remain relevant and valuable over time. For instance, an evergreen article on gardening tips will continue to attract readers long after its publication, as the information remains useful regardless of trends or seasons.
