Allium cepa aggregatum, commonly known as aggregatum onion or the multiplier onion, is a perennial vegetable belonging to the Amaryllidaceae family. It is considered a cultivar or variety of the species Allium cepa, which includes other popular onion varieties.
Allium cepa aggregatum is characterized by its unique growth habit, forming a cluster of multiple bulbs from a single planted bulb. The bulbs are typically smaller compared to other onion varieties and have a distinctive somewhat flattened shape. Each bulb comprises numerous small cloves or bulbels, rather than one solid, large bulb like typical onions.
This onion variety is renowned for its mild and sweet flavor, often preferred in dishes where a subtler onion taste is desired. It is commonly used for culinary purposes and can be cooked or eaten raw in salads, salsas, stir-fries, soups, and various other dishes. The leaves, known as scallions or green onions, can also be used as a garnish or added for extra flavor.
Allium cepa aggregatum is propagated by planting the small individual bulbels, which develop into mature bulbs in subsequent growing seasons. This characteristic enables the propagation of the plant by division, allowing it to spread and form larger clusters over time.
Overall, Allium cepa aggregatum is a unique onion variety known for its clustered growth habit, mild taste, and versatility in cooking.
