Two exceptionally fine flavoured varieties the result of 15 years of breeding. The textured ruffled leaves of Emerald Ice and Midnight Sun develop a striking contrasting centre as they mature and have the sweetest flavour – even the leaf stalks taste like candy and hold the crispiest texture.Sow in individual pots or a seed tray of good seed compost and cover with 6mm (1¼in) of compost or vermiculite, at a minimum of 15°C (60°F), until germination which takes around 5-7 days. Alternatively, can be sown thinly in a prepared seedbed 12mm (½in) deep, allowing 30cm (12in) between rows.Transplant when large enough to handle, about 5 weeks from sowing, to 50cm (20in) between plants each way. Plant firmly and keep well watered until established. Fleece against caterpillar and aphid as necessary, and net against pigeons during the winter.
