All that looks great @papa-pepper , I had to look up "Walking Onions", I've never seen anything with "bulbettes" on the stems.
I've seen yards FULL of tiny onion leaves growing everywhere in the grass, it smells like onion while cutting.
I always thought these were Chives that got loose.
We also used to have "wild Garlic" back home, they didn't make bulbs and cloves like normal garlic, but they did make a sort of clove, and the flavor/scent was milder than regular garlic. I used it to cook with a lot.
Tree onion, topsetting onions, walking onions, or Egyptian onions, Allium × proliferum, are similar to common onions (A. cepa), but with a cluster of bulblets where a normal onion would have flowers. Genomic evidence has conclusively shown that they are a hybrid of the common onion and the Welsh onion (A. fistulosum).[2] However, some sources may still treat the tree onion as A. cepa var. proliferum or A. cepa Proliferum Group. Tree onion bulblets will sprout and grow while still on the original stalk. They 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." It has been postulated that the name "Egyptian onion" derived from Romani people[3] bringing tree onions to Europe from the Indian subcontinent.
