Edible Qualities

Bunching Onion is an annual vegetable plant that is commonly grown for its edible qualities. The entire above-ground parts of the plant are edible, and are usually harvested from early summer to early fall. The edible parts have a zesty taste and a crisp texture.

The plant is most often used in the following ways:

  • Fresh Eating
  • Eating When Cooked/Prepared
  • Cooking
  • Baking

Planting & Growing

Bunching Onion will grow to be about 14 inches tall at maturity, with a spread of 4 inches. When planted in rows, individual plants should be spaced approximately 4 inches apart. This fast-growing vegetable plant is an annual, which means that it will grow for one season in your garden and then die after producing a crop. Because of its relatively rapid time to maturity, it lends itself to a second planting later in the season, after the first crop has been harvested; this will prolong the effective harvest period.

This plant is typically grown in a designated vegetable garden. It should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It may require supplemental watering during periods of drought or extended heat. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America.

Bunching Onion is a good choice for the vegetable garden, but it is also well-suited for use in outdoor pots and containers. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing the canvas against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
