Petunia exserta is a rare member of the genus Petunia, endemic to the Serras de Sudeste in southern Brazil. First described in 1987, only fourteen plants were found in the wild during an expedition in 2007.[1] In the wild, the plant is found growing only in shaded cracks on sandstone towers. It is the only Petunia species that is naturally pollinated by hummingbirds, and the only red flowered Petunia species.[2]
