Hardwood Timber Species Data: Blackbutt (Eucalyptus Pilularis)
Hardwood Species: Blackbutt
Blackbutt is a highly versatile timber. It’s a fantastic choice for not just solid timber floors but also engineered wood, parquetry, and decking.
With colouring from pale brown to cream, and with a cathedral grain pattern that’s been called “inspiring” by builders and interior designers alike, Blackbutt has a moderately coarse yet even texture thanks to its interlocking but overall straight grain.
As always, please remember that all types wood, being a natural product, feature massive amounts of variation when it comes to appearance, density, and hardness.
In fact, don’t be surprised if your blackbutt contains hints of pink hues, one of the most common colour variations for this versatile Australian hardwood.
Native to Southeastern Australia, Blackbutt (from an economic standpoint) is a Eucalyptus varietal that’s one of our country’s most important hardwoods.
Used not just as a food source for koalas but for the high quality of timber it produces, its ease of regeneration, and its relatively quick growth.
Blackbutt grows as tall as 50 meters, with an impressive average trunk diameter of 4.1 meters. Glossy to dark green leaves adorn these giants, and it features lovely white flowers from September to March.
Its bark is unique, rough from the ground to about halfway up, where it then gives away to smooth white bark instead. The charming common name of this tree comes from its appearance after fires, with the base appearing black. Mature heartwood tends to be pale yellow with brown notes, while sapwood is often much more pale in comparison.
