Leek 'Bleu de Solaise'

'Bleu de Solaise' is a stunning traditional French heirloom leek that is perfectly suited to the British winter. It is easily recognized by its beautiful, deep blue-green, almost purple-tinted foliage. This variety is exceptionally hardy and can be left in the ground throughout the coldest UK winters, to be harvested from December right through to April. The shanks are of medium length and very thick, with a delicious, melting texture and sweet flavour when cooked. For the best white shanks, leeks should be 'earthed up' or planted in deep holes as they grow. They prefer a sunny position in fertile, well-worked soil. Sowing usually takes place in spring, with transplanting to their final positions in early summer. As a slow-growing crop, they are often used to follow early salad crops or peas. Their resilience to frost and striking appearance make them a staple of the winter vegetable garden and a favourite for leek and potato soup.
