Petunia

Petunia is a Latin-origin flower name, taken from the genus Petunia of trumpet-shaped flowering plants. The word entered English from French petun, borrowed from the Tupi petyn meaning 'tobacco,' as the plants are related to tobacco. The name carries a cheerful, old-fashioned floral sweetness.

Petunia is a gloriously old-fashioned flower name that has been making a quiet comeback on the strength of its pure charm. The trumpet-shaped blooms it references come in a riot of colors and have a dependable, cheerful quality — which is exactly the personality most owners project onto pets who carry this name. It has a slightly comedic potential (Aunt Petunia in Harry Potter is famously unpleasant, which creates an amusing contrast for a beloved pet) while also being genuinely beautiful and floral.
