Nicotiana tabacum, or cultivated tobacco, is an annually grown herbaceous plant of the genus Nicotiana. N. tabacum is the most commonly grown species in the genus Nicotiana, as the plant's leaves are commercially harvested to be processed into tobacco for human use. The plant is tropical in origin, is commonly grown throughout the world, and is often found in cultivation. It grows to heights between 1 to 2 metres (3.3 to 6.6 ft). Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestris, N. tomentosiformis, and possibly N. otophora.[1]
