Welsh onion character and garden use
welsh onion seeds are a practical choice for gardeners who want a reliable, clump-forming onion herb with a clean, strong onion flavour. This variety is known as the Winterhecke welsh onion and is grown mainly for its upright, hollow leaves that can be harvested repeatedly through the season. As a perennial onion herb, it can return year after year in suitable conditions, making it a useful addition to herb beds, borders, and mixed kitchen gardens.
The plant forms sturdy, pipe-like foliage and develops into a hardy onion plant reaching around 40 cm in height. It is often used as a bunching onion in the garden, where the leaves are cut as needed for everyday cooking.
