Ilex opaca (American Holly)

Beautifully shaped, Ilex opaca (American Holly) is an upright, evergreen tree of symmetrical, dense, pyramidal habit with stout, stiff branches bearing leathery, dark green leaves, 2-4 in. long (5-10 cm), adorned with spine-tipped teeth. Ilex opaca is dioecious, with male and female flowers on separate trees. It produces abundant small greenish-white flowers in spring that are followed by a profusion of attractive bright red berries on pollinated female trees. Extremely showy, they ripen in fall, persist into winter and enliven the winter landscape unless they are devoured by birds.

American Holly is a favorite among birds, drawing in species like the American Robin, Cedar Waxwing, Eastern Bluebird, Northern Mockingbird, Northern Cardinal, and numerous others. Its vibrant berries and dense foliage offer valuable food and shelter, making it a cherished asset for birdwatchers and wildlife enthusiasts alike.
