Description

This plant produces small bulbs at the end of the flower stem that can be eaten or cooked. They have a strong onion flavor and are often used as pickled onions or added to salads. It is important to harvest the bulbs when they are well dried in order to store them. The bulbs can be eaten both raw and cooked. They can grow up to 4 cm in diameter and have a distinct onion aroma. When sliced, they make a tasty addition to salads and can also be used as a vegetable or flavoring in warm dishes. The leaves of this plant can also be eaten raw or cooked and have a strong onion flavor. They add a pleasant taste to salads, but it is important not to harvest them in large quantities as this can reduce the yield of the bulbs. The leaves are available from late autumn, but it is important to avoid harvesting them at a time when diseases like powdery mildew are encouraged.
