Significant advantage to the home gardener. Once mature, remains in harvest condition for several months. Very hardy with dense, dark green heads. An outstanding performer in difficult conditions.

Sow late winter to mid summer in a specially prepared seed bed or coldframe (for late winter) or for most reliable germination in seed boxes in heat. 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.
