Nicotiana tabacum, or cultivated tobacco, is an annually-grown herbaceous plant. It is found in cultivation, where it is the most commonly grown of all plants in the genus Nicotiana, and its leaves are commercially grown in many countries to be processed into tobacco. It grows to heights between 1 and 2 meters (3' to 6'). Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, Nicotiana tomentosiformis, and possibly Nicotiana otophora.
Attested since 1588, borrowed from Spanish tabaco. The Spanish word is either from Arabic طَبَاق (ṭabāq, “a type of medicinal herb”), also طُبَاق (ṭubāq), or from a Taíno word meaning "roll of tobacco leaves" or "a pipe for smoking tobacco".
