Also known as scallions or green onions, spring onions are in fact very young onions, harvested before the bulb has had a chance to swell.
Both the long, slender green tops and the small white bulb are edible, and are good either raw or cooked.
They have a similar flavor to onions, but are much milder. (source)

As you can see spring onions contain a little phosphorus and sugar, a huge amount of water, a hint of calcium, a hint of fat, and are quite acidic.
This means that unfortunately they can’t eat spring onions, they are too much for hamsters to handle and should be avoided as a food.
