Snowball have pure white globe shaped roots with lovely sweet and juicy flavoured white flesh making them the ever popular choice for spring sowing and successional use. The tops can also be used as tasty greens. Turnips are fast growing root vegetables which add a different flavour grated raw in salads, added to casseroles or served as a separate vegetable completely. When pulled young, they are a far cry from the woody, sad examples that can often be seen in the supermarkets today.
