Holly bushes are evergreen shrubs known for their glossy, dark green leaves and bright red berries. They belong to the genus Ilex and are commonly used in landscaping for their attractive appearance and ability to provide year-round color. Holly bushes can grow up to 15 feet tall, depending on the species, and are often pruned to maintain a desired shape. These plants thrive in well-drained soil and prefer partial shade to full sun. The berries are a food source for various birds, while the leaves can be spiny, deterring some herbivores. Holly bushes are also associated with Christmas traditions, often used in decorations and wreaths.
