Green Onion
Green onion refers to the immature stage of Allium cepa, harvested before the bulb fully develops, featuring long slender green stalks and a mild flavor prized in many culinary traditions.
Origin Story
Green onions are not a distinct cultivar but represent an early harvest stage of the common onion, Allium cepa. This practice of harvesting onions before bulb formation is ancient and widespread globally, with no single origin or breeder documented.
Classification
Botanically, green onions belong to the species Allium cepa and are considered immature onions rather than a separate variety. They are closely related to bulb onions but harvested early, and the term overlaps regionally with similar Allium species like scallions and spring onions.
Appearance or Form
Green onions feature elongated, hollow green leaves atop a slender, undeveloped white base that has not yet formed a full bulb. Their fresh, crisp texture and bright green stalks distinguish them from mature bulb onions.
Behavior or Usage
Green onions serve versatile roles in cooking, used both raw and lightly cooked. They add fresh, mild onion flavor and crispness as garnishes, salad ingredients, or aromatic bases in dishes worldwide, interacting closely with human culinary practices.

🌱Agronomy
Green onions mature quickly, typically within 30 to 60 days, and can be grown from seed or sets. They tolerate cooler climates better than mature onions and are often cultivated in succession for continuous harvest. However, they are vulnerable to pests like thrips and diseases such as downy mildew and basal rot.
🍳Culinary Uses
Widely used raw or lightly cooked, green onions enhance salads, stir-fries, soups, and serve as aromatic bases in diverse cuisines. Their tender green stalks and mild white bulbs add both flavor and texture, making them a staple garnish and ingredient worldwide.
🧊Storage And Preservation
Green onions require cool, moist storage and are not cured like mature onions. Best kept refrigerated, they maintain quality for about one to two weeks. Proper handling is essential to preserve their crispness and prevent wilting.
📦Market And Distribution
Green onions are commercially marketed in bunches for retail and foodservice sectors. They are a fresh product with year-round availability in some regions through protected cultivation. Unlike storage onions, they demand careful handling and refrigeration to maintain freshness during distribution.
