Holly trees (Ilex opaca) are evergreen trees with prickly, glossy green leaves and red berries. The tree grows in U.S. Department of Agriculture plant hardiness zones 6 through 9. Holly trees grow up to 40 feet tall, but they are slow growers gaining only about 9 feet every 20 years. They prefer full sun or light shade and rich, well-draining, slightly acidic soil. Growing hollies from berries is a slow task because they require a long stratification and germination period.
