Leeks contain vitamin C, vitamin K and folic acid, as well as the trace elements potassium, calcium, magnesium, iron and manganese. The antioxidant and antibacterial sulfur compound allicin, which is formed from alliin and the catalyzing enzyme allinase, causes the intense smell and taste of leeks.

Cultural History

The leek is a cultivated form of the field leek (Allium ampeloprasum), which occurs wild in the Mediterranean region and is cultivated in various forms.

Leeks are already around 2100 v. Chr. known; the Sumerian ruler Urnammu had it cultivated in the gardens of the city of Ur.

Leeks were also known in ancient Egypt; they are said to have served as food for the workers who built the pyramids.

In ancient times, the leek was appreciated throughout the Mediterranean area. The Roman emperor Nero is said to have appreciated leeks for the mustard oil they contain; because of this passion, Nero was also known as "Porrophagus" (Leek eater) denotes.

Leek was so sacred in ancient Germanic ritual that it gave the name to a rune.

It is probable that the leek came to Central Europe from Italy in the Middle Ages. In the British Isles, leeks are said to have been used by the British king Cadwallader around 640 as a distinguishing mark for his troops.

Cultivation

Leeks are still grown mainly in the Mediterranean region and in Europe, although in Germany they are mainly grown in North Rhine-Westphalia. It is sown in spring, transplanted around St. John’s Day (24. June) 24 cm from each other, and in the winter, in the garden, bake it quite deep so that the leaves bleach, or leave it in the country and cover it with straw.

Plants tolerate different neighbors growing directly adjacent to them differently:

  • Good neighbors are: Endive, strawberry, chamomile, cabbage, kohlrabi, lettuce, carrot, salsify, celery, tomato.
  • Bad neighbors are: Bean, peas, beet.
