Bunching onions are a fast-growing, perennial herb that produces multiple slender bulbs and tender green tops ideal for harvesting throughout the growing season. They're excellent for succession planting and provide a continuous supply of mild onion flavor for fresh use or cooking.
Why grow it
Bunching onions differ from bulbing onions in that they produce minimal bulb development and are primarily grown for their mild green tops and tender white bases. They tolerate closer spacing than bulbing varieties, making them efficient for small-space gardens, and regrow after cutting rather than requiring replanting each season. Unlike bulbing onions, they're better suited to succession planting for continuous harvest rather than storage.
Watch out for
Bunching onions may become stringy or tough if allowed to mature beyond the tender stage, so harvest timing matters more than with some other alliums. They perform best with consistent soil moisture and can decline in hot, dry conditions typical of mid-summer in many regions.
