Coral Trees

28 Aug, 2021

Coral Trees are large deciduous trees that are commonly considered to be weeds. Also known as flame trees, they have pea pod-shaped flowers varying from red to deep orange. A scattering of rose-like thorns characterises their light brown bark.

Although coral tree seed is infertile, the plant can spread through cuttings, roots or plant fragments fallen from the plant. Coral trees grow fast, live for a long time and have dense foliage which prevents native plants from becoming established. They are incredibly hardy and can live comfortably in a range of conditions.


Here is some advice to help you deal with Erythrina x sykesii.

Physical Control

Remove younger coral tree plants, making sure you dig up all the roots. Once out of the ground, leave the plant to rot on concrete surfaces. Be careful not to leave any soil on the plant as it can easily re-establish itself.

Other Treatment

To eradicate established coral trees, cut them back and then immediately paint with MetGel. Be careful not to paint other plants – particularly native species.


Note: Both of the products above may harm desirable plants that are in close proximity, care must be taken when applying.


When using sprays and chemicals always read the label and follow instructions carefully.
