Also known as kohlrabi or German turnip, this versatile root vegetable is a cultivar of the cabbage - there’s a turnip for the books!

Brassica oleracea gongyloides or Kohlrabi is a very unusual looking edible vegetable in the cabbage family. The name comes from two German words. Kohl meaning turnip and Rabi meaning cabbage. It gets this name due to the fact that it looks similar to a turnip. It has a mild and sweet taste. It will grow quickly, to a height of around half a metre. It can grow in most types of soil, even heavy clay but will prefer alkaline soil. The leaves are edible and so is the swollen stem that can be grated and used in a salad.

Kale 'Superschmelz'

PLANTS Brassica oleracea gongyloides 'Superschmelz'

Brassica oleracea gongyloides 'Superschmelz' is commonly called Kohlrabi ‘Superschmelz’. This is a giant variety of kohlrabi. Large vegetables are notorious for being tough and not at all tasty, grown for novelty rather than culinary purposes, but the huge swollen stems of this plant manage to maintain a sweet flavour and a juicy texture. It will grow between 8 and 10 inches in diameter (about the size of a turnip) and is pale green in colour. This variety likes lots of sun and lots of water too. The harvested vegetables store well in a cool place and can also be frozen.
