Outpaces and out yields all other Savoys. Savoy Cabbage King can produce a crop almost every season of the year, so you don't need to wait for winter to experience that delicious Savoy flavour.
Sow seeds late winter to mid summer in a specially prepared seed bed or coldframe (for later winter) or for most reliable germination in seed boxes in heat 19-21C (65-70F). Sow seeds very thinly 1cm (½in) deep in 15cm (6in) wide rows.
Transplant during late spring/ early summer, into a sunny site 46x46cm (18x18in) apart.
The soil should be well drained, with some humus, and firm, not recently dug.
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.
