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 seeds thinly in a nursery bed 1cm deep in rows 15cm apart in April of May. Thin the seedlings gradually to about 8cm apart. In June or July the plants should have 5 or 6 leaves, transplant to the growing site spacing them 30cm apart all round.
