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 same 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. An annual, most of the varieties seen in gardens are hybrids (P. × atkinsiana, also known as P. × hybrida).
The plants are herbaceous, generally hairy, and the flowers are funnel-shaped, with petals joined together. The fruit is a dry capsule with two compartments and many tiny seeds.
Petunia is a genus in the family Solanaceae, subfamily Petunioideae. Well known members of Solanaceae in other subfamilies include tobacco (Nicotianoideae), and the cape gooseberry, tomato, potato, deadly nightshades and chili pepper (Solanoideae). Some botanists place the plants of the genus Calibrachoa in the genus Petunia, but this is not accepted by others.Petchoa is a hybrid genus derived from crossing Calibrachoa and Petunia.
