Fun Facts
- 🌱 Aucuba Rozannie is self-fertile, meaning a single plant will produce berries without requiring a separate male pollinator plant—unlike most other Aucuba varieties which need cross-pollination.
- 🌱 The name 'Aucuba' comes from the Japanese 'ao-kiba,' meaning 'greenleaf plant,' and Aucuba japonica is native to Japan, China, and the Himalayas.
- 🌱 Despite being evergreen, Aucuba is extremely shade-tolerant and is sometimes called 'Japanese laurel'; it can thrive in areas so shaded that many other plants fail entirely.
