The Welsh Onion, or Bunching Onion, is a perennial species of onion native to China that is now grown around the world. Welsh Onions are very similar in taste and appearance to the common onion, Allium cepa. Large Welsh Onions resemble leeks and small ones look like chives. The main difference is that the stems of the Welsh Onion are hollow and their bulbs are barely thicker than their stems, which is why they are sometimes described as being "bulb-less." Plants form perennial clumps, which can be divided to propagate more onions. Welsh Onions can be grown as an annual in cooler regions where the plants cannot overwinter.
