Description

Bulb - can be used raw or cooked. This small bulb, with a diameter of up to 20 mm, has a subtle garlic flavor and can serve as a seasoning in salads and warm dishes. The bulb is harvested in early summer when the plant begins to wilt and can be stored for up to 6 months. Leaves - also usable raw or cooked as a substitute for garlic. The leaves are available from late autumn to spring. Young leaves are suitable for salads, while older leaves are delicious when cooked as a vegetable or as a seasoning. They have a milder and more delicate flavor than onions. Flowers - can be consumed raw. Juicy with a light garlic flavor, these flowers are a tasty and decorative addition to salads.
