Cauliflower Snowball is a superb heritage variety, first bred in America in the 1890's there probably still isn't a better cauliflower to grow in the garden. The pure white, snowball-sized heads can be harvested when small, 5cm (2in) or left to mature to 15cm (6in), they can also be forced.
Sow seeds from January to February under glass. March to May outdoors or in September to October in coldframes to over winter.
