Blackbutt Timber (Eucalyptus Patens)

Blackbutt Timber and Blackbutt Timber Decking

Blackbutt timber is a popular hardwood grown in the coastal regions of NSW and southern QLD.  It is one of the taller eucalypts and the trees can reach up to 50 metres in height.

There are many reasons for the popularity of Blackbutt timber including the two important ones noted below.

  1. Blackbutt timber is popular because the Blackbutt trees grow quickly thus making regeneration easy.
  2. Blackbutt trees are resistant to bushfires.  In fact it is from this bushfire resistance that Blackbutt trees were named.  After a bushfire has swept through, the Blackbutt tree’s buttress (or butt) is blackened from the fire, hence the name Blackbutt.
