Atherosperma moschatum


Also known as Blackheart Sassafras or Tasmanian Sassafras. Blackheart Sassafras is an under-storey evergreen tree, growing extremely well in the cool temperate rainforests of Tasmania and reaches heights of around 25 metres. Tasmanian Sassafras is not related to the Sassafras found on mainland Australia, it has distinctive qualities which include an oil that is highly aromatic smelling like cinnamon and the leaves have a sarsaparilla scent. Sassafras has the most variable and dynamic colouring, the most spectacular being the Blackheart Sassafras. The blackheart occurs in very few trees, it is an unusual viral fungus, which usually affects the tree after storm damage or crown damage. The fungus causes streaks through the heartwood, ranging from light brown through to purple, green and black. No two pieces of Blackheart Sassafras are the same and each saw log has its own unique features thus making each cut board a “one off” exclusive piece. Sassafras is highly valued in the furniture making industry for its ease of working, and beautiful creamy grey colour, and is regarded by many as an intermediate between softwood and hardwood.
