Ilex verticillata, commonly known as winterberry, is a deciduous holly native to eastern North America. It is prized for its bright red berries that persist through winter, providing food for birds. The plant thrives in wet, acidic soils and prefers full sun to partial shade. It is dioecious, requiring both male and female plants for berry production. Winterberry is popular in landscaping for its ornamental value and wildlife benefits.
