American Holly (Ilex opaca)
American Holly is a broadleaf evergreen tree, and it can grow 20-50 feet tall, and can occasionally reach 70 feet in height. The American Holly is known for its glossy spiky leaves and beautiful red berries, which makes it a very popular symbol during the Christmas season. Despite making a beautiful decoration, American Holly berries are poisonous to both humans and pets. An interesting fact about this tree is that it is a dioecious, which means that there are separate male and female trees. The berries are only produced by the female trees, while the male trees are needed for the pollination.
