Allium fistulosum
Also called Japanese Bunching Onion, Bunching Onion
Welsh onion (Allium fistulosum) is a perennial onion relative grown for its hollow, tubular leaves, used as a scallion or spring onion. It forms evergreen clumps that regrow after cutting, so it is easy to keep in a bed or pot.
Allium fistulosum, the Welsh onion, also commonly called Japanese bunching onion, stone-leek, and spring onion, is a species of perennial plant, often considered to be a kind of scallion.
A. fistulosum forms perennial evergreen clumps of tubular leaves up to 0.6 metres (2 feet) tall, topped by white umbels. It is commonly used in Asian cuisine.
The species was developed in Asia from a wild relative native to China. It is now widely cultivated for culinary use (being of ornamental value only when in bloom) and has been naturalized in North America and Eurasia.
A. fistulosum is an ingredient in Asian cuisine, especially in East Asia and Southeast Asia. It is particularly important in China, Japan, Taiwan and Korea.
