Establishment
3-6 monthsYoung shrub with minimal growth; developing root system. Foliage is present but plant is relatively small.
Water regularly to establish roots. Mulch base to retain moisture. Avoid heavy pruning; allow plant to settle into new location for first season.
Vegetative Growth
1-2 yearsSteady branching and leaf development. Plant fills out and gains height and width. Glossy green foliage becomes more prominent.
Apply balanced fertilizer in spring. Prune lightly if needed to shape. Maintain consistent moisture. Remove any dead or damaged branches.
Flowering
4-6 weeks (spring)Small, inconspicuous greenish or reddish flowers appear in spring, clustered in panicles. Flowers are not showy but are essential for berry set.
Avoid heavy pruning during flowering to prevent removing flower buds. Ensure adequate moisture and light exposure to maximize flower production.
Fruiting
Summer through winter (6-8 months)Flowers develop into bright red, glossy berries approximately 0.5 inches in diameter. Berries persist on branches through fall and into winter.
Berries are the main ornamental feature. Avoid excessive pruning during fruiting season. Light feeding with balanced fertilizer supports berry development.
Dormancy
2-3 monthsPlant enters semi-dormant period in late winter. Growth slows significantly while berries continue to provide color and ornamental interest.
Reduce watering frequency but maintain some moisture. Do not fertilize. Prune dead wood and shape plant as needed in late winter before new growth begins.

Fun Facts
- 🌱 Aucuba 'Rozannie' is one of the few female Aucuba cultivars that is self-fertile, producing abundant berries without requiring a male pollinator plant nearby—most aucubas require cross-pollination.
- 🌱 The name 'Rozannie' is a portmanteau reflecting its role as a breeding success, and this cultivar was specifically developed to provide reliable berry production in ornamental gardens.
- 🌱 Aucuba is sometimes called 'gold dust plant' because the species A. japonica 'Variegata' has distinctive yellow-spotted foliage; 'Rozannie' maintains the dark green leaves but excels in berry production.
