Welsh Bunching Onion, seed

Welsh Onion, also known as Nebuka or Welsh Bunching Onion, is a dependable perennial onion prized for its mild flavour, vigorous growth, and year-round usefulness in the kitchen garden. Unlike traditional bulb onions grown for a single harvest, this evergreen bunching onion forms dividing clumps that continue multiplying over time, creating a long-lasting and reliable supply of fresh onion greens and tender stems.

Native to eastern Asia, this traditional culinary onion has been valued for generations in home gardens and cooking for its versatility and ease of growth. Both the green tops and small elongated bulbs can be harvested and used much like shallots or spring onions, bringing a softer, sweeter onion flavour to soups, stir-fries, meat dishes, dumplings, broths, and savoury garnishes. Its mild taste makes it especially suited to fresh use where stronger onions may overpower a dish.

One of the standout features of Nebuka is its perennial, self-multiplying nature. Once established, plants rapidly divide to form dense clusters reaching approximately 50cm tall, allowing gardeners to harvest regularly while the plant continues regenerating. This makes it an excellent “cut-and-come-again” kitchen staple for productive edible gardens, raised beds, or cottage-style herb plots.

Welsh Bunching Onion performs best in moist, free-draining soils in a sunny open position. It is notably frost resistant, making it suitable for cooler climates and year-round growing in many parts of Australia, though it appreciates consistent moisture during dry conditions. Its resilience, productivity, and low-maintenance habit make it particularly valuable for gardeners seeking practical, useful crops that continue rewarding season after season.

With its combination of culinary versatility, perennial reliability, and traditional heritage, Nebuka remains one of the most useful onions for the productive home garden.
