A much milder flavour than the purple and white sprouting types. The hybrid varieties produce a large central green head and once this has been harvested, a second crop of smaller individual spears is produced where the leaf stem joins the main stem. Sow the seed in April or May into trays or modules under glass at 13c. Alternatively later sowings can be made outdoors into a seed bed in shallow drills 2cm deep. Once plants have 5 to 6 leaves transplant to final positions spacing plants 45cm (18") apart between plants and 45cm (18") between the rows.
