Leeks are part of the large onion family (Alliaceae) but are much quicker and easier to grow than onions. They are ready to harvest from 14 weeks from seed.
Leeks have thick, white, onion-flavoured ‘stems’ (actually leaf bases) that are usually prepared by being sliced. They are used to add a gentle onion flavour to foods or can be turned into their very own dish of potato and leek soup.
Leeks can be substituted for onions. They are low in calories but high in magnesium and vitamins A, C, and K.
