Evergreen plants are types of vegetation that retain their leaves throughout the year, rather than shedding them in the fall. This characteristic allows them to maintain their green appearance and continue photosynthesis, even in winter. Common examples of evergreen plants include pine trees, spruce, and holly. These plants are well-adapted to various climates, from cold regions to tropical areas. Their ability to keep leaves year-round helps them conserve water and survive harsh conditions. Evergreens play a crucial role in ecosystems, providing habitat and food for wildlife, as well as contributing to soil stability.
