Globe onion
The globe onion is the classic form of Allium cepa, recognized for its rounded, slightly flattened bulb and serving as the standard reference for most culinary and agricultural onion varieties worldwide.
Origin Story
Originating from the domestication of Allium cepa in Central Asia and the Middle East thousands of years ago, the globe onion evolved through centuries of selection for uniformity and storability. Its modern commercial forms result from extensive open-pollinated and hybrid breeding efforts across the United States, Europe, and Asia, though no single breeder or lineage defines this broad, landrace-based group.
Classification
The globe onion belongs to the species Allium cepa within the Amaryllidaceae family and represents a major market class distinguished by its rounded to slightly flattened bulb shape. It encompasses the majority of yellow, red, and white onion cultivars commonly grown and consumed worldwide, setting it apart from other forms like flattened, torpedo, or specialty onions.
Appearance or Form
Globe onions feature bulbs that are round to slightly flattened, typically measuring between 5 and 10 centimeters in diameter. Their outer skins vary in color—yellow, red, or white—while the inner flesh remains white. The bulbs have firm, tightly layered scales and dry outer skins, contributing to their characteristic texture and storability.
Behavior or Usage
Grown as annuals despite their biennial nature, globe onions adapt to diverse climates through varying daylength sensitivities, from short-day to long-day types. They produce medium to large bulbs with moderate pungency and varying sweetness depending on the cultivar. Their firm structure and flavor profile make them versatile in culinary applications and reliable for commercial cultivation with generally good disease resistance.

🌱Agronomy
Globe onions exhibit variable photoperiod sensitivity, including short-day, intermediate, and long-day types, enabling adaptation to a wide range of growing regions. They are biennial plants cultivated as annuals, producing high yields under commercial conditions. Their bulbs typically store well for three to six months post-harvest. Disease resistance varies by cultivar but is generally moderate, supporting broad agricultural success.
🍳Culinary Uses
Widely embraced in global cuisine, globe onions are used raw, cooked, and processed. Yellow globe onions are prized for cooking and caramelization, red types are favored fresh in salads and garnishes, and white varieties are common in Latin American and Mediterranean dishes. They form the flavor base for soups, stews, sautés, and countless recipes.
🧊Storage And Preservation
