Do Walking Onions really walk? I don’t know, but I do know that they propagate from babies ~ known as bulblets ~ and not seeds. I began growing them 3 years ago from 5 teeny weeny bulblets and now have a patch which some neighbors find quite “different”.
They are sometimes called Egyptian Walking Onions and Tree Onions ~ excellent in stir-fry dishes and not as pungent as shallots.
I leave the parent plants to grow and re-grow; replanting 30% of harvested bulblets in hope that 1 day I will have hundreds of parent plants among vegetables to deter and confuse pests with their odor.
These little ones, harvested today, will go into my vegetarian pasta dish as garnish/topping together with grated cheese.
