Botanical description

Nicotiana tabacum is a robust annual little branched herb up to 2.5 m (8.2 ft) high with large green leaves and long trumpet shaped white-pinkish flowers. All parts are sticky, covered with short viscid-glandular hairs, which exude a yellow secretion containing nicotine.[13]

Very varied in size, the lower leaves are the largest up to 60 cm (24 in) long, shortly stalked or unstalked, oblonged-elliptic, shortly acuminate at the apex, decurrent at the base, the following leaves decrease in size, the upper one sessile and smallest, oblong- lanceolate or elliptic.[13]

In terminal, many flowered inflorescences, the tube 5?6 cm (2.0?2.4 in) long, 5 mm (0.20 in) in diameter, expanded in the lower third (calyx) and upper third (throat), lobes broadly triangular, white-pinkish with pale violet or carmine colored tips tube yellowish white; calyx with five narrowly triangular lobes which are 1.5?2 cm (0.59?0.79 in) long.

A capsular ovoid or ellipsoid, surrounded by the persistent calyx and with a short apical beak, about 2 cm (0.79 in) long. Seeds are very numerous, very small, ovoid or kidney shaped, brown.[13]

Uses

Toxic parts

Whole plant

Nicotine deadly toxicity
All parts of the plant are poisonous[10][14][15][16]. They contain a volatile oil called nicotine, this is a virulent poison that produces nausea, vomiting, sweating, palpitations[17] and in sufficient quantity even death[5]. The nicotine of half a cigarette, when fully absorbed (which is not achieved through smoke inhalation), is sufficient to kill a fully-grown adult human[5].
The given value was not understood.

Medicinal uses(Warning!)

Tobacco has a long history of use by medical herbalists as a relaxant, though since it contains nicotine, a highly additive drug[18], it is seldom employed internally or externally at present[10][19]. The active ingredients can also be absorbed through the skin[10].

Propagation

Seed

Surface sow in a warm greenhouse about 10 weeks before the last expected spring frosts. The seed usually germinates in 10 - 20 days at 20°c. Keep the soil moist and pot up as soon as the plants are big enough to handle, planting them out after the last expected frosts.


Cultivation

Prefers a well-drained deep rich moist soil in a sunny position[20][21]. Plants are not very hardy in Britain, but they can be grown as biennials in areas where winter temperatures do not fall below about -5°c[21]. A polymorphic species[22]. Tobacco is very widely cultivated for its leaves, there are many named varieties[1]. As well as being used as an insecticide, the leaves are used to make cigarettes, cigars, snuff and for chewing. There are many long-term health problems associated with these uses, especially from cancer, lung, circulatory and heart diseases. The plant accumulates potassium[23]. The plant has sweetly scented flowers that release most of their scent in the evening and attract moths[24]. Plant requires more than 14 hours daylight per day in order to induce flowering[6].
