Allium x proliferum

Walking onion

  • Botanical name: Allium x proliferum
  • Common name: Walking onion
  • Family: Alliaceae
  • Plant Type: Vegetable

The walking onion, Allium x proliferum, has multiple uses and should be treated as a perennial crop as it self-seeds readily – effectively ‘walking’ around your garden. In spring its narrow green leaves may be harvested and eaten as chives. As the bulbs develop they may be harvested as spring onions, or left in the ground to harvest later as shallot-sized onions.

Any plants left in the ground will grow small bulbils at the tip of the leaves. As they become heavier these will cause the plant to bend down until the bulbils touch the ground, where they develop roots and grow into separate new plants.
