Question for Garlic experts

Hi all,
I have been growing garlic for the past 6 years & really enjoy growing them.
I have let 6 garlics go to flower and i have noticed the flowers have very small galic shaped bulbs on them.
Has anyone here ever grown them ? as i will be trying, but would like to know when to plant them ( before or after winter ?).
i realise it will take a few years for them to be of any size.
Many thanks
John 

The bits that are growing within the "scape" are called "bulbils".

As Argyllie say, they take a while to get anything worthwhile, 2 years from planting them now, in fact.

They are also lovely cooked with butter 

I find that planted bulbils need 3 years before they're a useful size, unless you prefer them small, hence 2 years for growth.

They are a faster way to produce more garlic as head will give you up to 6 plants, bulbils in a few years can give you up to 15 or so, but is it worth the wait by comparison?
