Romanesco produce a pale green head consisting of a mass of spirals. Flavour is sweeter and more delicate than many white cauliflowers with a lovely crunch especially raw with ‘dips’. Also an excellent steamed vegetable. Romanesco is rarely seen in the supermarkets so do try to grow yourself.Sow in individual pots or a seedtray of good seed compost and cover with 6mm (¼in) of compost or vermiculite, at a minimum of 15C (60F), until germination which takes around 7 days. Alternatively, can be sown thinly in a prepared seedbed 13mm (½in) deep, allowing 30cm (12in) between rows.Transplant seedlings when large enough to handle into larger pots, or transplant from the seedbed around 5 weeks from sowing. Allow 45cm between plants in the row and 60cm between rows. Plant firmly and water well until plants are established.
