I just completed my harvest of garlic and noticed that on a couple of stalks, a second head seemed to be forming about half way up the stalk. The head that formed in the ground was nice sized and seemed to be quite normal.

I am familiar with the bulbils that will form on the top of scapes, but that is not what I have. These are literally in the middle of the stalk.

There's a lot of wisdom on this site. Surely others have experienced this. Just looking for an explanation, if there is one.
