Sassafras is an under-storey evergreen tree, growing extremely well in the cool temperate rainforests of Tasmania and reaches heights of around 25 metres. Sassafras has the most variable and dynamic colouring, the most spectacular being the Blackheart Sassafras. The blackheart occurs in some, produced by a fungus, which usually affects the tree after some crown damage resulting from storms or adjacent falling trees. Sassafras is particularly good as a veneer or as a solid timber, with knots providing another striking feature. Sassafras is highly valued in the furniture making industry for its ease of working and versatility, and is regarded by many as an intermediate between softwood and hardwood.
