Fun Facts
- 🌱 Emerald Green Holly is a hybrid between Ilex aquifolium (English Holly) and Ilex rugosa (Japanese Holly), bred to be extremely cold-hardy while maintaining attractive characteristics of both parents.
- 🌱 Holly berries are toxic to humans and many animals if ingested in large quantities, containing compounds like caffeine and theobromine, but birds have evolved immunity to digest them without harm.
- 🌱 Male and female holly flowers are produced on separate plants; a male holly must be nearby for female plants to produce berries, and a single male can pollinate multiple females within 30-40 feet.
