Petunia is a genus of 20 species of flowering plants of South American origin. The popular flower of the same name derived its epithet from the French, which took the word pétun, 'tobacco', from a Tupi–Guarani language. A tender perennial, most of the varieties seen in gardens are hybrids.

In botany, a perennial plant or simply perennial is a plant that lives more than two years. The term is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth from trees and shrubs, which are also technically perennials. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world.
