About

Turnera subulata is a species of flowering subshrub in the passionflower family known by the common names white buttercup, sulphur alder, politician's flower, dark-eyed turnera, and white alder. Despite its names, it is not related to the buttercups or the alders. It is native to Central and South America, from Panama south to Brazil. It is well known in many other places as an introduced species, such as Malaysia, Indonesia, several other Pacific Islands, the Caribbean, and Florida in the United States.

It is commonly cultivated as a garden flower, but because of its high adaptability, it is also known as a garden weed.
