Egyptian Walking Onions

Tree onions, Allium ×proliferum, are similar to common onions, but with a cluster of bulblets where a normal onion would have flowers.

They are also commonly called top onions, topsetting onions, walking onions, or Egyptian onions. Tree onion bulblets will sprout and grow while still on the original stalk, which may bend down under the weight of the new growth and take root some distance from the parent plant, giving rise to the name walking onion.

A few were planted 3 years ago and they've been marching along big style ever since. We eat the stems as chives or spring onion, the bulbs pickled or just as onion cooked.
