A hybrid of horticultural origin, that was probably developed in Australia or New Zealand.
Occasionally naturalised in the coastal districts of southern and eastern Australia. It has been recorded from the coastal districts of New South Wales, near Perth in south-western Western Australia, in south-eastern and northern Queensland, and on Lord Howe Island.
Common coral tree (Erythrina x sykesii) is regarded as an environmental weed in many parts of New South Wales. It appears on numerous local and regional weed lists in this state (e.g. in the wider Sydney and Blue Mountains region and in the North Coast and South Coast regions) and is currently listed as a priority environmental weed in at least one Natural Resource Management region.
This species does not produce viable seed and only propagates vegetatively, via stem segments and suckers. Logs, branches and even twigs will grow into new plants and they break easily, thereby aiding its spread during floods. Common coral tree (Erythrina x sykesii) has spread from garden and street plantings into bushland areas, often aided by the dumping of garden waste. It is primarily a problem along creeks and rivers, but will also grow in disturbed natural vegetation and open woodlands.
In New South Wales it has been reported to replace native riparian vegetation, block the flow of creeks, increase creek bank erosion, and cause other trees to fall over. It has also been recorded from conservation areas, including Eurobodalla National Park and Murramarang National Park in the South Coast region. In south-western Western Australia it is reported to grow along river edges between Perth and Bunbury.
