What do you call this type of onion?

[Rainlights]

I call them scallions.

On rare occasion, I'll call them green onions.

[Eace]

It's green onion (vihersipuli) in Finnish, but in English I'd call it a scallion.

[obdigore]

Scallions or Green Onions, like most other native english speakers, apparently.

[Butler to Baby Sloths]

Spring Onion

Actually on taking another look, I was getting chives and scallions mixed up. I stand corrected.

These things are proving to be super controversial.

Green Onion. I was under the impression that leeks were rather like a jumbo sized green onion (and while similar, not the same) - but that picture offers no banana for scale. The white part below I guess would be scallions, while the green part up top would be the green onion part.

Scallions or a leek. Thank far fetched from Pokemon for teaching me leek

That is a pic of both a green onion (the bottom) and scallions (the top).

I have done quite extensive research recently about this plant's exact name too since i was cultivating some and it's just one big mess. It's called green onion almost everywhere (back home in french "oignon vert") but it's never the same plant.
Everything is genus Allium but back home it's Allium Chinense apparently or Allium Fistulosum, then there's all the hybrids... and the youngs onions... and then i said **** it !

Well, leeks can be twice the length of a banana..... but the green parts of a leek really don't get used much - or maybe at all - in the USA.

I make a cream of potato and leek soup that just rocks.

Northwest here...we call them both green onions and scallions...mostly just delicious.

So says google:

A scallion, green onion, or spring onion, is one of various Allium species, all of which have hollow green leaves (like the common onion), but which lack a fully developed root bulb. Harvested for their taste, scallions are milder than most onions. Used as a vegetable, it is eaten either raw or cooked.

I always thought the proper name for them in the english language was leek. Isn't it then?

No that is a completely different plant.

No that is a completely different plant.

I'm taking note. Thank you.

We call it "mlada kapula" or "kapulica" which translates to "young onion"
