Question
what is the difference between scallions, chives and green onions?

Answer
Dear Lindsey,
Chives and green onions are different plants.  Chives grow in a clump and the flavor is in the greenery above the ground.  Green onions grow individually and have a small white bulb underground that is edible and contains the most pungent of the flavor.  Scallions are young green onions before the bulb develops.
Kind Regards,
