Ilex verticillata, commonly known as winterberry, is a deciduous holly native to North America. It is recognized for its bright red berries that persist through winter, providing a striking contrast against its bare branches. This shrub typically grows in wetland areas and can reach heights of 3 to 12 feet. Its glossy green leaves turn yellow in the fall, adding seasonal interest to gardens. Winterberry is not only beautiful but also beneficial for wildlife. The berries are a vital food source for birds like American robins and cedar waxwings during the colder months. Additionally, it can be used in landscaping as a natural privacy screen or as part of a native plant garden.
