Casuarina glauca – Swamp Oak, She-Oak, Grey Oak, River Oak

Casuarina glauca is commonly called the ‘Swamp Oak’ due to the wood’s oak-like appearance and natural occurrence near brackish waterways. They are often called ‘native pines’ because the foliage bears a similarity to pine needles.

Like other Casuarinas, a beautiful feature of this tree is the gentle rustling sound it produces when the weather is windy.

This is a fast growing tree, that returns nitrogen to the soil and is very good for remediating areas affected by salinity and seasonal water-logging. Tolerant of dry spells once established, frost tolerant. Heavy frost may brown the top foliage, but new growth will shoot away in spring.
