Chinese onion or Allium chinense is an evergreen vegetable characterized by its white, crisp bulbs, long green stalks, and tiny, purple flowers. It is cultivated in Asia and its leaves and bulbs can be consumed either raw or cooked, adding a depth of flavor to a variety of dishes.
The flowers, which bloom in autumn, are sometimes used as a garnish. The strong, pungent odor of Chinese onion is thought to act as a repellent for moles and other garden vermins. This vegetable can also be pickled and served as a side dish or as an appetizer in Asian cuisine.
