  • Overview

    Japanese bunching onions are delicate, slender green onions that mature in approximately 65 days. Unlike bulbing onions, they form elongated white shanks with tender green tops, making them ideal for both raw and cooked applications. These heirloom varieties are prized for their mild, sweet onion flavor and exceptionally crisp texture. They're a staple in Japanese cuisine, perfect for garnishing dishes, stir-fries, and salads. Their easy growing requirements and continuous harvest potential make them a favorite among home gardeners seeking fresh, flavorful alliums.
