When large bulbs of the potato onion are planted, they form a number of small bulblets, each with a leafy top. These can be harvested while green as green onions. If allowed to ripen, they are small bulbs suitable for planting the following year. The potato onion varieties rarely set seeds, so are propagated by the small bulbs. When grown for the bulbs, culture is in all ways similar to that for common onion.
Production in the U.S.: No separate data.
Use: Dry bulbs as cooked vegetable, and in culinary and salad. Green onion mainly as salad.
Part of plant consumed: Bulb after outer scales removed, or leaves and immature bulbs as green onions.
