âEvergreen Long White Bunching Onionsâ seedlings. Some people refer to immature common onions as scallions. Before the onion plant has formed the large bulb weâre all familiar with, it has a white area near the roots and long, green, hollow leaves. At this point, they look, and taste, just like scallions. So itâs reasonable to call them scallions. But in reality, theyâre just immature bulbing onions. Green onions, or onion greens, simply refers to the leaves of the onion plant, which some people prefer due to their milder flavor.
