Scallions are the small immature plants of lily (allium) family root vegetables such
as onion, shallots…etc. Some of the common names used are spring onions, green
bunching onions...etc. Precisely speaking, the term spring onions denotes to the bulb
including its top greens of Allium fistulosum (welsh onion), a sub-species in the
broad allium family, especially in the west.

In general, spring onions are young immature plants harvested very early before the
plant grows further big and its bulb becomes larger. For the same purpose, they are
planted closely in the fields in order to stunt the growth of bulbs.
