Inflorescence: flowers 1 in axils of leaves or leaf-like bracts.

Species In Genus: +- 30 species: generally South America; some cultivated for ornamental, sometimes waifs. Etymology: (Petun, Native American word for tobacco) Note: Petunia axillaris (Lam.) Britton, Sterns & Poggenb., Petunia violacea Lindl. may be naturalized in California.
Unabridged Note: Evidence from chloroplast DNA, morphology, and ecology was used by Fregonezi et al. [Taxon 61:120--130. 2012] to support segregation of Calibrachoa from Petunia, as well as recognition of Calibrachoa parviflora (Juss.) D'Arcy, which was said to occur "in North America and Europe, probably as a result of introduction from South America and subsequent naturalization".
