Culture of the highest grades of tobacco

Tobacco (Nicotiana tabacum) is native to Central America, from where it spread to North and South America and other countries of the world, gaining worldwide fame in some places for its high qualities.
According to the color of the flower, tobacco is divided into three types, each of which has different breeds. Tobacco varieties with a pink flower in different shades, from white-pink to crimson-red, belong to one type, to another type - with a yellow-green flower, and to the third - with white.
Of these three types,
only the first is important for the production of higher grades of tobacco,
since all the best grades of smoking tobacco are obtained from most of its breeds: other
breeds are more suitable for the preparation of snuff.
Types of tobacco with yellow-green and white flowers do not play any role in the
production of higher grades.
