Fun Facts
- 🌱 Southern Gentleman is a male cultivar, meaning it produces flowers but no berries—its sole purpose is pollination, making it the 'bachelor' of the winterberry world used to ensure berry production on female cultivars.
- 🌱 Winterberry hollies are native to eastern North America's swamps and wet forests, earning them the nickname 'swamp holly,' and they are among the few holly species that are deciduous rather than evergreen.
- 🌱 The bright red berries produced by female winterberries pollinated by Southern Gentleman can persist on branches well into winter, turning darker and becoming more attractive to hungry birds as other food sources deplete.
