Pereskia grandifolia) is a species of cactus native to eastern and southern Brazil.

Young twigs are green or reddish with conspicuous white spots marking the stomata.

The dense inflorescence develops at the ends of stems and also laterally from the areoles of upper parts of the main shoots and twigs.

Molecular phylogenetic studies from 2005 onwards suggested that with this circumscription, Pereskia was not monophyletic, and consisted of three clades.

It is widely cultivated in other parts of South America, the West Indies and beyond, and has become naturalized in some of these countries, including Vietnam.

violaceus is apparently native to Espírito Santo and Minas Gerais, but is cultivated in neighbouring states.
