Fun Facts
- 🌱 Possumhaw viburnum's berries are among the last to be consumed by birds in winter, meaning they serve as an emergency food source when other fruits have depleted.
- 🌱 The plant's common name 'possumhaw' derives from the Native American word for the plant, reflecting its long history of use by indigenous peoples.
- 🌱 Unlike many viburnums, possumhaw requires cross-pollination with another viburnum cultivar for optimal berry set, making planting multiple plants more rewarding for berry production.
