Allium cepa var. aggregatum (Potato Onion)

The Potato Onion, also known as Nesting Onions or Multiplier Onions, is a member of the onion family that is reproduced primarily by division of bulbs. Continuously harvested permaculture onion once established. Similar to shallots, Potato Onions have a sharper flavor and store better. Large bulbs range from ½”-2″and can be replanted indefinitely making them more manageable than biennial onions which must be grown from seed each year. They do best in humus rich, well-drained soil and are well suited to container gardening. Photo courtesy of The Gardeners Almanac UK.
