Fun Facts
- 🌱 Lilly pilly is native to rainforests of northeastern Australia and the Indo-Pacific region, and its name likely derives from the Aboriginal word 'lilly-pilly' or similar variations in indigenous languages.
- 🌱 The vibrant colored new growth—often red, pink, or copper—is a natural deterrent to herbivorous insects, as the pigments indicate less-palatable, nutrient-poor young leaves.
- 🌱 Some lilly pilly varieties produce berries so abundantly and in such striking colors that they are primarily grown as ornamental trees, though most berries are still technically edible bush tucker.
