River Oak

Casuarina cunninghamiana, commonly known as river oak, river sheoak or creek oak, is a species of flowering plant in the family Casuarinaceae and is native to Australia and New Guinea. It is a tree with fissured and scaly bark, sometimes drooping branchlets, the leaves reduced to scales in whorls of 6 to 10, the fruit 7–14 mm (0.28–0.55 in) long containing winged seeds (samaras) 3–4 mm (0.12–0.16 in) long.

Casuarina cunninghamiana belongs to the Casuarina genus within the Casuarinaceae family. It performs reliably across temperate, subtropical zones in our experience. It is an Australian native we grow and specify regularly.
