The Potato onion (also known as an "Old-Time Hill Onion) is a type of Multiplier Onion.

When planted, a small bulb will grow to become one large onion. Conversely, when a large potato onion is planted, it will create many smaller bulbs. This characteristic is what makes it a multiplier onion.

In temperate climates, potato onions are best planted in the fall to produce a higher yield. Onions can be pulled for green onions or scallions in the spring. Onions left to grow to maturity should be dug and dried after the tops have died (usually in July/August)
