About
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 native to Bolivia, commonly grown throughout the world and often found in cultivation. It grows to heights between 1 and 2 metres (3.3 and 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.
Where it grows
N. tabacum is a native of tropical and subtropical America, also appearing as a weed.
Uses
The plant is native to the Caribbean, where the Taíno people were the first recorded peoples to use it and cultivate it. In 1560, Jean Nicot de Villemain, then French ambassador to Portugal, brought tobacco seeds and leaves as a "wonder drug" to the French court. In 1586 the botanist Jaques Dalechamps gave the plant the name of Herba nicotiana, which was also adopted by Linné. It was considered a decorative plant at first, then a panacea, before it became a common snuff and tobacco plant.
