Scallion vs. Escallion

Main Difference

The main difference between Scallion and Escallion is that the Scallion is a one of various Allium species and Escallion is a species of plant.

• Scallion

  Scallions (also known as green onions or salad onions) are vegetables of various Allium onion species. Scallions have a milder taste than most onions. Their close relatives include the garlic, shallot, leek, chive, spring onion and Chinese onion.Although the bulbs of many Allium species are used as food, the defining characteristic of scallion species is that they lack a fully developed bulb. Allium species referred to as scallions have hollow, tubular green leaves growing directly from the bulb. These leaves are used as a vegetable; they are eaten either raw or cooked. The leaves are often chopped into other dishes, in the manner of onions or garlic.

• Escallion

  Allium fistulosum, the Welsh onion, also commonly called bunching onion, long green onion, Japanese bunching onion, and spring onion, is a species of perennial plant.

  The species is very similar in taste and odor to the related common onion, Allium cepa, and hybrids between the two (tree onions) exist. A. fistulosum, however, does not develop bulbs, and possesses hollow leaves (fistulosum means “hollow”) and scapes. Larger varieties of the A. fistulosum resemble the leek, such as the Japanese negi, whilst smaller varieties resemble chives. A. fistulosum can multiply by forming perennial evergreen clumps. It is also grown in a bunch as an ornamental plant.
