Extremely popular salad vegetable in Europe but now gaining a large following over here. Slightly more biting flavour than lettuce. The plants can be grown for use throughout the summer and autumn either in the vegetable plot or for earlier use in polytunnels or under cloches. Sow the seed thinly 1cm deep from March onwards in rows 30cm apart. Thin the seedlings to eventual spacings of 25-30cm apart. Successional sowing gives a continutiy of supply. First heads should be ready about 10-12 weeks from sowing.
