Summary
Nothing stands out in the winter landscape like the bright red berries of holly, and winterberry is no exception. Unlike American holly, this shrub loses its leaves in autumn, so the berries that follow are all the more evident. This tough native tolerates heat, drought, and soil compaction, and is resistant to deer foraging, fire, and salt. It makes a nice border or hedge for moist areas, is an excellent choice as a specimen for adding winter interest, and is also popular as a foundation planting.
Gardener’s note: Winterberries, like all hollies, are dioecious (separate male and female plants). Only fertilized female flowers will produce berries, so plant at least one male for every 6-10 female plants.
