Mexican petunia (Ruellia simplex) is an evergreen herbaceous perennial recognized by its wrinkly, trumpet-shaped light purple or white flowers. It is commonly cultivated as an ornamental plant.
Due to its vigorous spreading ability, Ruellia simplex has become widely naturalized outside Mexico. It is considered an invasive species in many countries
Plants of the genus Ruellia are normally shrubby ornamental plants that grow both outdoors and indoors. They are easy to grow in warm areas, requiring very little care.
