Tradescantia zanonia

Tradescantia zanonia, formerly known as Campelia zanonia, is an evergreen perennial subshrub of the dayflower family, closely related to Tradescantia zebrina. It is native to the tropical Americas, ranging from Mexico through Central America and the Caribbean to Bolivia and southern Brazil. Its common names include cañagria, cascajo flor, cinta, rascadera, and suelda.

Its capsule is covered by the fleshy purple-black calyx, hence a berry-like appearance.

It is cultivated as a greenhouse ornamental. There is a variegated cultivar named 'Mexican Flag'.
