Fun Facts

- 🌱 The berries can persist on branches well into winter, providing critical food for migratory birds during cold months when other food sources are scarce.
- 🌱 Despite having both male and female flower parts, most viburnum species produce better fruit when cross-pollinated by another viburnum plant, rewarding gardeners who plant more than one.
