Outpaces and out yields all other Savoys. It 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 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 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.
