Scallion, green onion, spring onion and salad onion are English names (with many other regional names throughout the world) for various Allium species. Scallions have a milder taste than most onions. Its close relatives include the garlic, shallot, leek, chive, and Chinese onion.
The bulbs of many Allium species are used as food. But the defining characteristic of scallion species is that they lack a fully developed bulb. In common with all Allium species, scallions have hollow, tubular green leaves, growing directly from the bulb. These leaves are used as a vegetable; they are eaten either raw or cooked. The leaves are often chopped into other dishes, in the manner of onions or garlic.
