Allium fistulosum — Ailéam Síoraí
The Welsh onion is the answer to a question every gardener asks: why can't spring onions be perennial? These are. Plant once, and you have mild, hollow-stemmed onion greens to cut year after year. The more you cut, the more they produce.
Despite the name, Welsh onions have nothing to do with Wales — the name derives from an old word meaning 'foreign'. They've been cultivated in Asia for over 2,000 years and were widespread in European gardens until modern spring onions displaced them.
The white pom-pom flowers in summer are excellent for bees. Completely hardy in Irish conditions.
