Petunia exserta
''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.〔(【引用サイトリンク】title=Petunias Rare and Red )〕 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.
==Description==
''P. exserta'' has a bright red corolla with distinctive exserted stamens and stigma, the latter which are typically associated with hummingbird pollination. It share the erect habit, and similar corolla, pollen, and stalk attributes as ''Petunia axillaris'' and ''Petunia secreta''. The flowers have no fragrance, which is not necessary for attracting hummingbirds, who have little sense of smell.〔 The red color is due to several anthocyanin pigments, which are different from the cause of red color in modern hybrid petunias.〔
