Chromolaena odorata
Also called Paraffin Weed, Siam Weed, Siamweed, Crucita, Bitterbush, Butterfly Weed, Devilweed
Jack in the bush is a fast-growing, weedy, multi-stemmed shrub from the Americas, now invasive in many tropical regions. It thrives in full sun and disturbed ground, and is best treated as a weed rather than a garden plant.
Chromolaena odorata is also known as jack in the bush. It is a tropical and subtropical species of flowering shrub in the family Asteraceae. It is native to the Americas, from Florida and Texas in the United States south through Mexico and the Caribbean to South America. It has been introduced to tropical Asia, West Africa, and parts of Australia.
Chromolaena odorata is toxic to cattle and is larvicidal against all major mosquito vectors. It can also cause allergic reactions.
