I grow Chesnok Red garlic, and I remove the bulbils so flowers and seeds can develop. I just did that today, and now I would estimate I have two or three cups of bulbils. They're really small and dry out quickly, but if planted soon a lot of them will grow small garlic for next year. If cared for properly, they'll grow to full size in another year or two. If anybody wants some in the next week or so, PM me an address.
I can do the same for for the so called walking onions/top multiplying. Make excellent green onions. This time of year produce bulbils on top. If not harvested they fall over and take a step to start a new cluster of onions.
