Fun Facts

  • In Germany, the plant hardly forms seeds, but reproduces via root pieces.

  • It belongs to the crucifer family (Brassicaceae), the same plant family as mustard, rocket and cabbage.

  • The flowering period is from May to July.

  • It lives for several years and generally flowers and fruits annually (perennial plant).

  • The flowers are pollinated by insects.

  • Endangerment level Germany: not evaluated
  • Usage:

    In folk medicine, horseradish is used to treat digestive disorders. However, it can cause stomach and intestinal problems if consumed in excess.

  • Originally, the horseradish comes from south-eastern Europe. However, it has been planted in Central Europe since the 15th century and has often gone wild. It therefore probably belongs to the non-native species (neophytes) in Germany.

  • The origin of the name horseradish has only indirectly to do with the animal. In fact, the upper parts of the plant are inedible for humans as for grazing animals. A horse would also reject the pungent taste of the root. In this case, however, the name rather refers to something large, coarse or rough. It also appears in various other plant names, e.g. horsemint, horseparsley, horsevetch, and horsechestnut .

  • The roots taste hot and spicy due to mustard oils and are suitable as a seasoning for sauces and meat. Medicinally, the bactericidal and blood circulation stimulating effect is used.
