Hardwood Timber Species Specification Data: Timber Species: Spotted Gum (Eucalyptus maculata)
Hardwood Species: Spotted Gum
Species Description: Spotted Gum
A tall, straight-trunked tree that gets its name from the distinctive mottled weathering pattern on its outer bark layers, the Spotted Gum typically reaches 45 meters in height. There have been some reports of this eucalyptus varietal reaching rarefied heights of up to 90 meters or more, but this is exceedingly rare.
A flowering tree that attracts common Australian birds known as honeyeaters in droves, the spotted gum benefits from this arrangement as honeyeaters are thought to be one of the great pollinator species of the region. Spotted gum trees are found growing wild in Victoria, New South Wales, and Queensland in open forest and seem to grow best in dry, relatively infertile soil with a high slate and shale content, perhaps relying on honeyeaters to help them propagate and pollinate to ameliorate the limiting factors of such poor soil conditions. However, this popular tree has been naturalised to grow in South Australia and Western Australia, and its distinctively smooth, powdery bark with polygonal flakes and spots is highly recognizable across the country.
With timber colors ranging from pale, greyish browns to soft cream to even a rich, luxurious chocolate brown, spotted gum often produces attractive fiddle-back effects in its frequently wavy grain. It’s an exceedingly robust timber with a hardness rating of 11 on the Janka scale and a density of 950 kg/m³. Offering excellent termite resistance, spotted gum is ideal for solid timber flooring, engineered wood, parquetry, and decking; this warm, welcoming brown wood is an attractive choice for nearly any décor.
Dry Density: range 950 kg/m³
Janka Hardness: 11.0 kN
These properties are only a guide, as timber is a natural product there will be variations within any species. The Janka Dry Hardness rating measures the hardness of the wood. The higher the number the harder the wood.
