Casuarina equisetifolia

Family : Casuarinaceae

The Beach She Oak is a very hardy plant that grows on the fore dunes. It provides shelter and protection to more fragile plants and holds the dune together. She Oaks grow 10 – 15 metres tall and have pendulous branches. It has unusual needle like leaves that hang from branches, silvery green in colour with a blue tinge.

The flowers are tiny and differ between male and female flowers. Male flowers are in spikes and female flowers are globular and form a cone. These appear generally in the early dry but also sporadically through the year. Numerous tiny seeds are contained in rounded, woody cones that open when seeds are ripe. The spiky fruit ripen from April to September. The Beach She Oak attracts Black Cockatoos. It is a beautiful and wispy tree well suited for growing in exposed coastal areas.
