The Welsh Onion (Allium fistulosum) is the ultimate cut-and-come-again staple for a sustainable kitchen garden. Unlike common onions that are harvested once, this hardy perennial onion forms permanent, ever-expanding clumps of hollow, tubular leaves. A native of Asia despite its name, it is a remarkably resilient, providing a long season of mild, onion-flavoured greens.

Whether grown in a dedicated herb border or a patio pot, its architectural creamy white globe flowers make it as beautiful as it is productive. Perfect for those who want a never-ending harvest of fresh spring onions without the need for seasonal replanting.

Uses & Expert Tips

In the Kitchen & Bar

  • Authentic Cuisine: A vital ingredient in Jamaican and Asian cooking. Use the stems as escallion to season rice and peas, or flash-fry the white bases in stir-fries for a sweet, mild crunch.
  • Salads & Slaws: Finely slice the hollow tubes to add a mild, sweet onion bite to fresh salads, potato salads, or homemade coleslaw.
  • Soup & Stew Base: Because they are more robust than supermarket spring onions, they hold their shape beautifully when added to soups, ramen, or miso.
  • Edible Flowers: The white spherical flowers are entirely edible! Pull them apart and scatter the tiny florets over dishes for a decorative, peppery onion zing.

Expert Care Tips:

The more you harvest Welsh Onions, the more they grow. To ensure a constant supply of tender stems, always harvest from the outside of the clump and never take more than a third of the plant at once. For the best results, harvest whole clumps in June to refresh the growth, or snip individual leaves year-round.

Packaging is great and the advice and guidance offered by this knowledgable team is simply the best. 10/10 would recommend and would only by my plants from this lovely team."

"These lovely folk had the unusual rosemary we had been searching for in lovely growth and good price. Feel more than confident to mail order from them in future too. Also, their Rau Ram (vietnamese coriander) has lovely subtle flavour that we'd never tried before ."
