About Welsh onion
Allium fistulosum, commonly known as Welsh onion or spring onion, is a perennial herbaceous plant highly valued for its vibrant green, tubular, and hollow leaves. It forms attractive clumps of foliage resembling small leeks. It is ideal for vegetable gardens, garden borders, and pots, where its fresh leaves can be continuously harvested.
Native range
Central Asia and Siberia
Care tips
It prefers full sun to partial shade exposure and regular watering to keep the substrate moist but not waterlogged. The ideal soil is fertile, well-drained, and slightly acidic to neutral. A common mistake is not harvesting the leaves regularly, which can make them tough and diminish their flavor; cut them from the base to encourage new growth.
How to save a dying Welsh onion
