A green onion (also called a scallion or spring onion) was an onion harvested while still immature.[1][2] They had a milder flavour than fully-mature onions, and were typically eaten raw and used in salads or sauces, or as a garnish.[1][2]

The Gurdyroot, a magical plant, was described as looking like a green onion.[3]
