Fun Facts
- 🌱 Casuarina verticillata is often called a 'she-oak' because its fine, hair-like branchlets were once said to resemble women's hair; the drooping form led to its other common name 'drooping she-oak.'
- 🌱 Despite looking like a conifer with needle-like foliage, Casuarina verticillata is actually a flowering plant in the family Casuarinaceae; its needle-like structures are modified branchlets, not true leaves.
- 🌱 The tree's wood has been traditionally used in Australia for tool handles and small timber work due to its density and hardness, earning it nicknames like 'she-oak' timber among craftspeople.
