What is daun bawang in english?

Allium cepa L. var. Aggregatum contains shallots and potato onions, also referred to as multiplier onions. The bulbs are smaller than those of common onions, and a single plant forms an aggregate cluster of several bulbs. They are propagated almost exclusively from daughter bulbs, although reproduction from seed is possible. Shallots are the most important subgroup within this group and comprise the only cultivars cultivated commercially. They form aggregate clusters of small, narrowly ovoid to pear-shaped bulbs. Potato onions differ from shallots in forming larger bulbs with fewer bulbs per cluster, and having a flattened (onion-like) shape. However, intermediate forms exist.

In English, Daun bawang (Allium cepa L. var. aggregatum G. Don) is known by Multiplier onion, Potato onion, or Shallot.

Allium fisulosum (also known as the Japanese bunching onion) was historically the main allium vegetable of China and Japan where it has been cultivated for more than 2000 years and remains very important. While growing, the Japanese bunching onion is very similar in appearance to the common onion, but it does not form dormant bulbs. They have been grouped into four major types: the Kaga, Senju, Kujyo and Yagura negi.

In English, Daun bawang (Allium fistulosum L.) is known by Japanese bunching onion or Welsh onion.

Welsh onion

"Welsh onion" derives from old German "welsch" meaning foreign, as the species is native to China. Allium fistulosum is not indigenous to Wales or particularly common in Welsh cuisine; it is Allium ampeloprasum (the leek) which is the national vegetable of Wales.
