Leek, Mechelen Blue Green Winter (Organic)

Allium ampeloprasum.

Selected for over 15 years for winter hardiness down to -10°F in Mechelen, Belgium. Not an especially long leek, this variety puts its growth energy into growing fat instead of tall. Thick giant leeks are very highly regarded in Belgium and are an important winter food. A selection of the heirloom Blue Green Winter. From a biodynamic seed grower in Mechelen, Belgium.


Sow indoors in flats with good potting soil February to April. Transplant into the garden in April or June, when plants are at least the size of a pencil lead. Space 6” in rows that are 1’ apart. Leeks benefit from frequent watering and shallow cultivation. Harvest as needed throughout autumn and winter.

Seed Saving

To save seed, leave 20+ plants in the ground through the second spring and summer. Large globe shaped flowers attract pollinators. Isolate from other leeks by at least ½ mile.
