Begonia is a genus in the flowering plant family Begoniaceae and is a perennial. The only other members of the family Begoniaceae are Hillebrandia, a genus with a single species in the Hawaiian Islands, and the genus Symbegonia which more recently was included in Begonia. "Begonia" is the common name as well as the generic name for all members of the genus.
The genus name, coined by Charles Plumier, a French patron of botany, honours Michel Bégon, a former governor of the French colony of Haiti. It was adopted by Linnaeus.
