An absolutely gorgeous heirloom French variety with a fantastic flavour and steely blue leaves that make a beautiful addition to the ornamental border – they're particularly beautiful dusted with frost. It's one of the hardiest leeks around, so you can leave it in the ground right through winter until you're ready to harvest its sturdy white shanks.
Growing instructions:
Sow direct into shallow drills in a well-prepared seedbed in spring, and thin seedlings to 1cm apart. When seedlings are about pencil thickness, transplant to their final growing place, leaving 15cm between plants. For the longest white stems, dib a hole for each plant 15cm deep and drop the seedling in before filling the hole with water. Mulch plants with straw when the cold weather starts to prevent the soil freezing and you'll be able to get your leeks out of the ground right through winter.
