Eucalyptus Camaldulensis | Red River Gum

Red River Gum is an iconic Australian timber prized for its brilliant red colour. It ranges from red to reddish brown. Texture is relatively fine and even. Grain is usually interlocked and often wavy, producing an attractive "fiddelback" pattern. Gum veins are common. Can be used for both interior features and exterior construction.


Scientific Name: Eucalyptus Camaldulensis


Preferred Common Names: Red River Gum




The eucalypt originates in Australia where it has a wide distribution across the country. Eucalyptus Camaldulensis grows throughout South Africa, particularly in the Western Cape, Northern Cape, Gauteng and Free State. It was introduced to South Africa in the mid to late 1800's.

The specie is found in privately owned farm woodlots, windbreaks, tree lined avenues and riparian zones.

River Red Gum yields a beautiful red to reddish brown timber. It is classified as a "Class 1 Heavy Hardwood" for above ground applications and a "Class 2 Heavy Hardwood" for in ground applications.



It It is particularly suited to situations requiring high strength where appearance is also important. If left untreated externally it will turn a silvery grey colour overtime. Red River Gum polishes to an elegant finish sometimes displaying characteristics such as fiddle back. It has a fine interlocked grain.
