Discover Welsh Onion

• The Welsh onion, Allium fistulosum L. (green onion, Japanese bunching onion, spring onion, escallion), is a member of the onion family, Alliaceae. 
• The names are ambiguous, as some may also be used to refer to any young green onion stalk, whether grown from Welsh onions, traditional bulbing onions, or other members of the onion family, in particular scallions, a separate species of Allium. 
• Next to culinary use, it is also grown in a bunch as an ornamental plant.

Know your Welsh Onion - Botany

• The species originated in Asia, possibly Siberia or China.
• The species is very similar in taste and odour to the related garden onion, Allium cepa, and hybrids between the two (tree onions) exist, see Tree Onion. 
• The Welsh onion, however, does not develop bulbs, and possesses hollow leaves ("fistulosum" means "hollow") and scapes. 
• Large varieties of the Welsh onion resemble the leek, such as the Japanese 'negi', whilst smaller varieties resemble chives. 
• Many Welsh onions can multiply by forming perennial evergreen clumps. 

Know your Welsh Onion - Name Origins

• Historically, the Welsh onion was known as the 'cibol'.
• The name "Welsh onion" has become a misnomer in modern English, as Allium fistulosum is not indigenous to Wales. "Welsh" preserves the original meaning of the Old English word "welisc", or Old German "welsche", meaning "foreign".
