Toni, I haven't grown any garlic since 2016-17. I am now in Vero Beach, FL and because it's so difficult to grow good garlics without cold weather (freezes), I haven't even tried to grow any here. I might plant a large pot or two of a couple of varieties that are supposed to grow in FL. Time will tell.
I can't tell you about growing garlics from bulbils. I always shipped the scapes with the garlic bulbs and always planted cloves of the varieties I wanted to grow.
