Welsh onion, also known as Japanese bunching onion, is a versatile and flavorful herbaceous plant widely used in culinary dishes. It resembles a large green onion, with long, slender, hollow leaves and a mild onion flavor. Welsh onions are commonly used as both a garnish and a flavoring agent in Asian cuisine, particularly in Chinese, Japanese, and Korean dishes. They can be chopped and added raw to salads, soups, stir-fries, and noodle dishes, or cooked briefly to soften their texture. Welsh onions are prized for their fresh, oniony taste and are a staple ingredient in many savory recipes. They are easy to grow and are popular in home gardens for their culinary versatility and ornamental value.
