Well-known for being robust and resilient, these leeks are often grown for winter hardiness and are said to survive even under heavy snow. Their short stature and stout stems make them a good choice for growing in a windy spot too. Sow indoors, from January to February, 0.5cm deep, in a tray of compost. Water well and place in a cold frame or unheated greenhouse. Keep moist. Transplant 5cm apart to other trays, when large enough to handle. Gradually accustom young plants to outside conditions before planting out, from May to July, into well-cultivated, fertile soil. Harvest from October to March. Or sow outdoors March - April
