About

Ruellia nudiflora, the violet ruellia or violet wild petunia, is a perennial plant in the acanthus family (Acanthaceae) found in North America. Despite the genus Ruellia being known as the wild petunias, they are not true petunias and are not closely related to them. The species thrives in disturbed areas and can sometimes be considered a weed.

Where it grows

The boundary between the native range and invasive range of R. nudiflora is not fully understood. The species is found in Texas in the United States, throughout Mexico and Central America, and in the Caribbean. It has invasive properties in the Caribbean islands and some regions of Mexico, especially the Yucatán Peninsula, where it is considered a weed.
