Evergreen shrubs are plants that retain their leaves throughout the year, providing consistent greenery in gardens and landscapes. Unlike deciduous shrubs, which lose their leaves in the fall, evergreen shrubs maintain their foliage, making them popular for creating privacy screens, hedges, and decorative borders. These shrubs come in various sizes and shapes, ranging from low-growing varieties like boxwood to taller options such as holly. They are often chosen for their ability to withstand different climates and their low maintenance requirements, making them a practical choice for gardeners looking to enhance their outdoor spaces year-round.
