Camphor Laurel (Cinnamomum camphora) is a large evergreen tree that grows up to 20-30 metres tall. The leaves have a glossy, waxy appearance and smell of camphor when crushed by hand. In spring it produces bright green foliage with masses of small white flowers. It produces clusters of black berry-like fruit around one centimetre in diameter.

Camphor Laurels have very stout trunks. They also have somewhat pale bark that is very rough and fissured vertically.

Camphor Laurel is native to Taiwan, southern Japan, southeast China and Indochina, where it is also cultivated for camphor production.

In the Anime My Neighbor Totoro, the Totoro lives in a Camphor tree and the plant is featured prominently in the story.

Camphor Laurel as an invasive species in Australia

Camphor Laurel was introduced to Australia in 1822 as an ornamental tree for use in gardens and public parks. It has however become an endemic weed throughout Queensland and northern New South Wales where it is suited to the wet, subtropical climate.

It is unsuited to the fragile ecosystems of Australia. It has been declared a noxious weed for the entire states of Queensland and New South Wales. Its massive and spreading root systems disrupt urban drainage and sewerage systems and degrades river banks. Its leaves have a very high carbon content which damages water quality and freshwater fish habitats when they fall into streams and rivers. The camphor content of the leaf litter helps prevent other plants from germinating successfully, helping to ensure the Camphor's success against any potentially competing vegetation, and the seeds are attractive to birds and pass intact through the digestive system, ensuring rapid distribution. Camphor laurel invades pastures, and also competes against eucalyptus trees which are the sole food source of koalas, which are an endangered mammal in many parts of eastern Australia.
