The largest variety of bunching onion is the White Spear Bunching Onion. As a gardening and landscaping expert, I can tell you that this particular onion produces thick white stalks that are cylindrical in shape and measure about 5-6 inches long. The stalks are topped by 6 inches of blue-green leaves, which adds to their attractiveness.
I have personally grown White Spear Bunching Onions in my own garden, and I can attest to their impressive size. When harvested, the stalks are substantial and provide a satisfying crunch when used in various culinary dishes. The white color of the stalks adds a beautiful contrast to the green leaves, making them visually appealing in the garden as well.
One of the advantages of growing White Spear Bunching Onions is their versatility in the kitchen. The thick stalks are perfect for grilling or sautéing, as they hold up well to heat and retain their shape. They can also be used raw in salads or as a garnish, providing a mild onion flavor that is not overpowering.
In terms of growing conditions, White Spear Bunching Onions prefer full sun but can tolerate some shade. They are relatively easy to grow and can be planted either from seeds or sets. When planting from seeds, it is important to space them out properly to allow room for the bulbs to develop. Onions are also known to benefit from regular watering and well-drained soil.
When it comes to harvesting, you can start to harvest the White Spear Bunching Onions when the stalks reach the desired size. Simply cut them off at ground level, leaving the bulbs in the ground to produce more stalks. This continuous harvest method allows for a prolonged supply of fresh onions throughout the growing season.
To summarize, the White Spear Bunching Onion is the largest variety of bunching onion available. Its thick white stalks and blue-green leaves make it a visually appealing addition to any garden. With its versatility in the kitchen and ease of cultivation, it is a popular choice for both amateur and experienced gardeners alike.
