Reference data

Nicotiana attenuata

Nicotiana attenuata is a species of wild tobacco known by the common name coyote tobacco. It is native to western North America from British Columbia to Texas and northern Mexico, where it grows in many types of habitat. It is a glandular and sparsely hairy annual herb exceeding a meter in maximum height. The leaf blades may be 10 centimeters long, the lower ones oval and the upper narrower in shape, and are borne on petioles. The inflorescence bears several flowers with pinkish or greenish white tubular throats 2 to 3 centimeters long, their bases enclosed in pointed sepals. The flower face has five mostly white lobes. The fruit is a capsule about a centimeter long.  is a species of wild tobacco known by the common name coyote tobacco.

Nicotiana benthamiana

Nicotiana benthamiana is a close relative of tobacco and species of Nicotiana indigenous to Australia.

The herbaceous plant is found amongst rocks on hills and cliffs throughout the northern regions of Australia. Variable in height and habit, the species may be erect and up to 1.5 metres or sprawling out no taller than 200 millimetres. The flowers are white.


Nicotiana glauca

Nicotiana glauca is a species of wild tobacco known by the common name tree tobacco. Its leaves are attached to the stalk by petioles (many other Nicotiana species have sessile leaves), and its leaves and stems are neither pubescent nor sticky like Nicotiana tabacum. It grows to heights of more than two meters.

Tree tobacco is native to South America but it is now widespread as an introduced species on other continents. It is a common roadside weed in the southwestern United States, and an invasive plant speciesin California native plant habitats.

The plant is used for a variety of medicinal purposes and smoked by Native American groups. The Cahuilla Indians used leaves interchangeably with other tobacco species in hunting rituals and as a poultice to treat swellings, bruises, cuts, wounds, boils, sores, inflamed throat, and swollen glands. Contains the toxic alkaloid nicotine. Ingestion of the leaves can be fatal.  It is being investigated for use as a biofuel.

Nicotiana sylvestris

Nicotiana sylvestris is a species of the genus Nicotiana, known by the common names woodland tobacco, flowering tobacco, and South American tobacco. It is a perennial plant, native to South America, and is often grown in gardens for its scented flowers. As it is not hardy, in temperate climates it is best grown as a biennial. The scent is strongest at night, so as to attract pollinating moths. The leaves are simple, somewhat sticky, with the blade partially surrounding the stem (clasping petiole). Flowers are produced on many-branched stems. The flowers are tubular, white, borne in large clusters above the foliage. Flowers can be over 7 cm long with a face 2 cm wide. Each flower eventually produces a large quantity of small seeds.

This plant has gained the Royal Horticultural Society's Award of Garden Merit.

This plant is thought to be one of the parents of Nicotiana tabacum, the plant used in modern tobacco production.


Nicotiana tabacum

Nicotiana tabacum, or cultivated tobacco, is a perennial herbaceous plant. It is found only in cultivation, where it is the most commonly grown of all plants in the Nicotiana genus, and its leaves are commercially grown in many countries to be processed into tobacco. It grows to heights between 1 to 2 metres. Research is ongoing into its ancestry among wild Nicotiana species, but it is believed to be a hybrid of Nicotiana sylvestrisNicotiana tomentosiformis, and possibly Nicotiana otophora.
