Winterberry (Ilex verticillata) is a deciduous holly native to eastern North America that lights up the winter landscape with brilliant red berries long after its leaves have fallen. This slow-growing shrub thrives in zones 3 to 9 and reaches 72 to 96 inches tall and wide, with an upright-rounded habit that works beautifully as a hedge or in rain gardens. The insignificant spring flowers give way to the plant's true glory: showy red berries that persist through winter and draw birds by the dozens. Hardy, low-maintenance, and tolerant of wet soils and clay, winterberry transforms challenging garden spots into wildlife magnets.

Red berries that persist long into winter are the signature feature of this deciduous holly, creating color when most gardens have faded to brown. Winterberry thrives in the wet, boggy conditions where many ornamentals fail, making it invaluable for rain gardens and low-lying areas. Its hardiness across zones 3 to 9 means gardeners from cold climates to the upper South can enjoy this native shrub. Because it's dioecious, you'll need both a male and female plant for berry production, but the payoff is seasons of vivid color that feeds hungry birds through the harshest months.
Winterberry serves as a hedging shrub and a key component of rain gardens and wet-site plantings where conventional ornamentals struggle. Its primary role is ornamental and ecological: the plant draws birds throughout the winter months, providing essential food during lean seasons when natural berry sources have been exhausted. It thrives in landscape designs focused on wildlife support and native plant restoration, making it popular among gardeners committed to creating habitat.

“Winterberry is native to the swamps, damp thickets, low woods, and stream banks of eastern North America, where it evolved to thrive in waterlogged soils that would kill most ornamental shrubs. The plant has long been part of the regional landscape, and certain forms reflect local adaptation. The variety Ilex verticillata var. padifolia, found in Missouri, represents a distinct population that occurs only in the southeastern part of the state, growing in the specialized habitat of granite rocky stream beds and sandstone bluffs in just four counties. This regional form exemplifies how winterberry has differentiated across its native range, making it not just a plant species but a living record of eastern North American ecology.”
