About
Clerodendrum quadriloculare (known as the bronze-leaved clerodendrum, fireworks plant, Philippine glorybower, shooting star or starburst bush in English, and bagawak or bagawak morado in Filipino) is a species of flowering plant native to New Guinea and the Philippines. It is one of many species previously included in the family Verbenaceae, but transferred to the Lamiaceae based on molecular studies. The plants produce flowers which look good in a garden, but it can be difficult to eradicate.
Where it grows
The bronze-leaved clerodendrum is native to the Philippines and Papua New Guinea, and has also been recorded from American Samoa, the Federated States of Micronesia, Fiji, French Polynesia, Guam, the Marshall Islands, the Northern Mariana Islands, Palau, Rarotonga in the Cook Islands, and Samoa, as well as Puerto Rico, Singapore, and Hawaii. As well as parks and gardens, it is found on road verges and on disturbed ground, pastures, forest edges and undisturbed forests where it is able to displace native species.
