Petunia is genus of 35 species of flowering plants of South American origin, closely related to tobacco, cape gooseberries, tomatoes, deadly nightshades, potatoes and chili peppers; in the family Solanaceae. The popular flower of the same name derived its epithet from the French, which took the word petun, meaning "tobacco," from a Tupi–Guarani language. Most of the varieties seen in gardens are hybrids (Petunia × hybrida).
