Black turnip - what is it?

Black turnip, also known as black radish (lat. Raphanus sativus) is a plant belonging to the Brassicaceae family, which can reach 90 cm in height. Its leaves are rough and feathery separated, and they are arranged in the shape of a dense rosette. The stem, which appears at a later stage of development, is distinguished by purple or white flowers. The fruit of the plant, in turn, is an oblong siliqua. Black turnip is a large and bulbous root, which is black on the outside, while on the inside - white and juicy. The plant is distinguished by its pungent taste and smell.

Black radish prefers a temperate climate. It is favoured by sunny places, which are distinguished by loamy and moist soil. Due to its short growing season, it is also often used as an aftercrop. Early varieties of black radish are usually sown at the turn of March and April. Late varieties can be sown in June or July. The cultivation of black turnip was common in the Middle East, Europe and Central Asia as early as the Ancient times. According to the prevailing belief, the black radish was then served to the workers building the pyramids in Egypt to give them strength to perform superhuman efforts.

The plant probably came to Poland during the reign of the Piast dynasty. Although the times of its greatest popularity have passed, it should not be forgotten that in the past it was a basic component of food. However, she lost the fight for favours among the housewives with the potato.

Currently, black turnip in the wild can be found on the coast of the Mediterranean Sea. In Poland, only cultivated varieties of plants are known.
