    Bred for its excellent flavour, this sturdy and reliable calabrese is also high-yielding and disease-resistant, especially to white rust. It produces its big, generous heads early in the season, especially from sowings made under glass in spring. Once the main head is cut, it produces a second harvest of smaller, deliciously tender side-shoots from the stem. Store gluts of calabrese by trimming sprigs and blanching in boiling water for a couple of minutes before packing loosely into bags and freezing.

  • Growing Instructions:Early sowings can be made into pots or seed trays under cover: pot on as the seedlings grow. Or sow later in spring into shallow drills in a well-prepared seedbed, thinning seedlings to 5cm apart. When plants reach 15cm tall transplant to where they are to grow, spacing about 30cm apart. Protect from slugs and net against pigeons.

  • Sow: May-June

  • Harvest: July-August
