Chinese tallow tree is deciduous ornamental tree. It is fast becoming an invasive environmental weed of water courses and native vegetation areas. Unfortunately it is still widely available from nurseries under its previous scientific name, Sapium sebiferum.
Chinese tallow tree is a fast growing tree that can quickly form dense tickets. Each tree produces thousands of seeds that can remain dormant for many years. It is also able to alter the chemical composition of the soil, enhancing conditions for further seed germination and rapid plant growth. This allows it to replace native species in a relatively short period of time.
In the USA, Chinese tallow tree has become a serious problem in many states. It is considered one of America’s worst weeds and is described as virtually impossible to eliminate once established.
Chinese tallow is a deciduous tree growing to 15 m high, but more commonly reaches heights of 6–10 m. The tree canopy can extend 4–5 m wide with long, drooping branches.
Fruit / seed pod
Chinese tallow tree is native to China and has naturalised in Japan, Taiwan, India, Pakistan, Europe, Martinique, Sudan and the USA. It has been cultivated for centuries for many purposes such as oil, fuel and dye.
Originally introduced to Australia as an ornamental tree with beautiful coloured foliage. It has been planted in streets and garden in southeast Queensland and northern New South Wales (NSW). Naturalised populations have now been identified in various locations throughout southeast Queensland. The largest infestation of Chinese tallow tree exists near Casino, NSW. Smaller infestations are evident throughout the North Coast, Central Coast and New England regions of NSW. Localised plants also exist in Victoria.
Chinese tallow tree is still actively promoted by gardening websites as an attractive deciduous tree for warm temperate and sub-tropical climates. Seeds can still be imported into Australia.
Chinese tallow tree reproduces by seed and root suckers. Seeds are taken by birds to new locations. Mature seed pods float and are carried in floodwater. Pods accumulate along the receding shoreline, releasing their seeds into the soil.
Plants re-shoot from the stump and roots after cutting and burning. Intentional planting of Chinese tallow tree still occurs.
Trees flower in late spring and early summer, with fruits following in late summer to autumn. Both males and female flowers can exist on the same plant, allowing self pollination. Mature trees can produce up to 100 000 seeds per year.
Chinese tallow tree is able to grow in a variety of habitats ranging from full sun to part shade. It prefers sub-tropical climates and also grows well in temperate areas that experience warm winters.
Preferring wet areas, it will flourish in places such as the edge of rivers, lakes, streams and swamps. It still grows well in drier conditions, including roadsides and disturbed areas. Chinese tallow tree is drought and flood tolerant.

Chinese tallow tree has a milky sap that is toxic to humans. Always wear protective clothing when treating plants.
Small plants and seedlings can be manually removed. Roots must be fully removed using this method as trees can quickly regenerate from root suckers. Manual removal is best conducted when the ground is soft and plants are easier to remove without breaking the root.
Best methods of herbicide treatment are with cut stump or stem injection application. This can be applied at any time of the year. Always monitor control efforts. Treat any shoots that have re-generated from the stump.
Trees treated with herbicide can make the foliage more attractive to stock. Remove livestock from treated areas to avoid possible poisoning.

It describes the state and regional priorities for weeds in New South Wales, Australia.
|All of NSW||General Biosecurity Duty
All plants are regulated with a general biosecurity duty to prevent, eliminate or minimise any biosecurity risk they may pose. Any person who deals with any plant, who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable.
Exclusion zone: whole region excluding the core infestation area of Richmond Valley Council, Ballina Shire Council, Lismore Council and Kyogle Council, Byron Shire Council and Tweed Shire Council
Regional Recommended Measure*
Whole region: The plant or parts of the plant should not be traded, carried, grown or released into the environment. Exclusion zone: The plant should be eradicated from the land and the land kept free of the plant. Land managers should mitigate the risk of the plant being introduced to their land. Core infestation area: Land managers should reduce impacts from the plant on priority assets.
