Provide nearby male holly for pollination if berry production desired; maintain regular watering
Fruiting
Late summer through winterSmall black berries develop on female plants; berries persist through fall and winter, providing ornamental interest and wildlife food
Fertilize with potassium-rich formula to support fruit production; maintain consistent watering; no harvesting needed unless removing for propagation

Fun Facts
- 🌱 Ilex crenata is also known as 'Japanese Holly' and is completely unrelated to the traditional American or English hollies (Ilex opaca), despite sharing the common name—it belongs to the same genus but a different species group.
- 🌱 Schilling's Dwarf is a female cultivar, meaning it produces berries, but requires a male holly nearby for pollination; male cultivars include 'Convexa' and other non-fruiting varieties.
- 🌱 This holly can live 50+ years with proper care and is often used in bonsai cultivation due to its fine foliage, slow growth, and ability to develop aged characteristics relatively quickly compared to other bonsai species.
