Second only to impatiens in annual bedding plant sales, the petunia has been a popular plant for many years due in large part to its ease of culture and non-stop flowering from spring to frost. Petunia is a genus of 20 species native to South America and the genus is loosely derived from an old Guarani word meaning “tobacco” since the two plants are both in the nightshade family.
