Fun Facts
- 🌱 Understory dogwood is native to eastern North America and gets its common name 'pagoda dogwood' from its distinctive horizontal branching pattern that resembles Asian pagoda architecture.
- 🌱 Unlike most dogwoods, this species has alternate leaf arrangement rather than opposite leaves, which is visible along the horizontal branches.
- 🌱 The berries change from red to blue-black as they ripen, and birds often strip entire crops from the branches in late summer, making it an excellent wildlife-supporting plant.
