Created a great deal of interest when grown at the Scottish Horticultural Research Institute, yet it is very widely grown in Northern Italy. The 'spears' can be snapped off individually or all together. It has a taste and texture exceeding the finest broccoli and to really appreciate the flavour it should be cooked and served individually with melted butter.
Sow in a well raked, firm, seed bed in late spring in drills 10mm (½in) deep and keep moist. Sowing can also be made under glass at this time.
Romanesco is ready in late autumn and the whole head need not be harvested all at once - just snap off the individual heads you need. Romanesco should not be grown on the same piece of ground two years running or follow other Brassicas (Cabbages, Sprouts etc).
Calabrese and Broccoli contain many healthy antioxidants. They are high in Vitamin A and C and are a good source of iron.
