Scallions (also known as green onions leaves or spring onion leaves) are vegetables derived from various species in the genus Allium. Scallions have a milder taste than most onions. Their close relatives include garlic, shallot, leek, chive,[1] and Chinese onions
Scallions may be cooked or used raw as a part of salads, salsas or Asian recipes. Diced scallions are used in soup, noodle and seafood dishes, sandwiches, curries and as part of a stir fry. In many Eastern sauces, the bottom half-centimetre (quarter-inch) of the root is commonly removed before use.

In Mexico and the Southwest United States, cebollitas are scallions that are sprinkled with salt, grilled whole and eaten with cheese and rice. Topped with lime juice, they are typically served as a traditional accompaniment to asado dishes.[8][9]

In Catalan cuisine, calçot is a type of onion traditionally eaten in a calçotada (plural: calçotades).

In Japan, tree onions (wakegi) are used mostly as topping of Japanese cuisine such like tofu.

In China, scallion is commonly used together with ginger and garlic to cook all kinds of vegetables and meat. The white part of scallion is usually fried with other ingredients while the green part is usually chopped to decorate finished food.

Welsh onion is the main ingredient in the dish cháo hành, which is a rice porridge used to treat the common cold.

In India, it is eaten raw as an appetizer. In north India, coriander, mint and onion chutney are made using uncooked scallions. It is also used as a vegetable with Chapatis & Rotis.

In the United Kingdom, scallions are sometimes chopped and added to mashed potatoes, known as champ particularly in Northern Ireland, or as an added ingredient to potato salad.

In the southern Philippines, it is ground in a mortar along with ginger and chili pepper to make a native condiment called wet palapa, which can be used to spice dishes or as a topping for fried or sun-dried food. It can also be used to make the dry version of palapa, when it is stir fried with fresh coconut shavings and wet palapa.

During the Passover meal (Seder), some Persian Jews whack each other with scallions before singing the song "Dayenu", symbolizing the whips endured by the Israelites under the ancient Egyptians.[12]

Scallion oil is sometimes made from the green leaves. The leaves are chopped and lightly cooked, then emulsified in oil that is then used as a garnish.

Although the bulbs of many Allium species are used as food, the defining characteristic of spring onion species is that they lack a fully developed bulb. Allium species referred to as spring onions 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.
