Green Onions

Also scallion, spring onion, salad onion

Taxonomically, a green onion is the same species (Allium cepa) as a common onion and a “sweet” onion. Or it is a different species, Allium fistulosum. Or it is a cross of the two. In case you don’t think this scientific description is helpful, just try finding a common one, as I have tried, by showing farmers, distributors, and “just plain folks” in different regions of the country the photo at the top and asking for names of the green-topped whatever-they-may-bes!
