Walking onions (Allium cepa var. proliferum) produce bulbs above ground on tall stalks. As the stalks mature, they drop to the ground, a few inches away from the roots. The bulbs at the top of the stalks root and grow a new plant. Over several seasons, the plants will travel across the ground. Walking onions grow in U.S. Department of Agriculture plant hardiness zones 5 through 9. Though a perennial, walking onions are commonly grown as an annual crop. Other common names include Egyptian walking onion, tree onion and top onion.
