Kohlrabi is botanically the same plant as cabbage. The stalks and leaves can be used in stir fries, soups and coleslaw making it very versatile.

Hello Noel, Kohlrabi is a swollen stem, not a root, tuber or bulb and it forms above the ground. To achieve good results ensure watering is consistent to avoid stringiness or bitterness. Trust this helps.
