About Winterberry Holly

Winterberry Holly is a beloved native shrub that provides an unparalleled burst of color during the bleakest months of the year. This deciduous holly typically grows 6 to 12 feet tall and is famous for the dense clusters of brilliant red berries that cling to its bare branches long after the leaves have fallen in autumn. These berries are not just beautiful; they are a vital winter food source for over 40 species of birds, including bluebirds and cedar waxwings. Native to swamps, thickets, and moist woods across eastern North America, it is perfectly suited for wet or heavy soils where other shrubs might fail. It thrives in full sun to partial shade and is an excellent choice for rain gardens, pond edges, or as a seasonal screen. It is important to note that Winterberry is dioecious, meaning you generally need both a male and a female plant within 50 feet of each other to ensure the female produces those iconic red berries. With its multi-season interest and immense wildlife value, it is a true cornerstone of the native landscape.
