The Welsh onion is perennial and hardy, so it can be harvested as a permanent crop over many years.
The leaves can be used like chives or as spicy leafy vegetables and the tender onions like spring onions.
Historically, the Welsh onion was used as a spring onion.
Their purple inflorescences are eye-catching in the vegetable garden and can be used in salads and as a garnish.
It shoots in early spring and brings early harvests when most other crops are still a long way off.
