This is a hardy winter cabbage, not even severe frost seems to bother it. The heads are crisp and crunchy with good flavour and the leaf is a conifer-blue colour.
Sow outdoors in a well prepared seed bed in spring, or alternatively, in a greenhouse or frame. Sow thinly 12mm (½in) deep in rows 23cm (9in) apart. If the soil is dry, water well and allow to drain before sowing.
Hoe occasionally and water if the weather is dry. Harvest in very late winter.
Eaten raw or cooked, cabbages are an excellent source of Vitamin C. Try to use all healthy outer leaves, as the darkest green leaves contain the most nutrients.
