The southern sassafras or blackheart sassafras, is an evergreen tree native to the cool temperate rainforests of Tasmania, Victoria, and New South Wales in Australia. It is common in the rainforests of Tasmania and Victoria, but more scattered and rare in the higher altitudes of eastern New South Wales. The northernmost area is at Mount Grundy, west of Port Macquarie. It is a small to medium-sized tree, growing around 6 to 25 m tall. However, in Tasmania, it can reach heights exceeding 40 m and a width of 1 m. It can be identified by the conical shape, the pale green leaves, and fragrant scent. It is found in the gullies and creek beds of high-altitude temperate rainforest, commonly associated with southern beeches of the genus Lophozonia. The timber is in demand for panelling, turnery, musical instruments, and other specialty work, (carvings, dishes, and boxes for tourists). The staining of the black heartwood is caused by fungus and makes the timber markings particularly attractive. The springy wood has been used for clothes pegs, and the scented bark is made into a beverage. It requires moisture and shade for cultivation, hence is not commonly seen cultivated.
