Root vegtable
The black radish is a root vegetable of the family Brassicaceae and is a variety of winter radish. It is also called Black Spanish radish or Erfurter radish.
The edible root has a tough black skin and white flesh. There are round and elongated varieties. Like other radishes, black radish has a sharp flavor due to various chemical compounds that the plant primarily uses as pest defense. Some of these phytochemicals are produced in high concentrations.

Generally, black radish is bigger than spring radish varieties and grows around seven to ten centimeters in diameter or length. The plants can grow up to a height of 0.5 m (20 in). Depending on the variety, the radishes are round, cylindrical or elongated.
