LEEKS gone to seed

I have left a few Leeks to go to seed with a view to deriving some sets from them. I was led to believe that little leeks seedlings would develop among the cluster of seeds but nothing is happening. What should I do with the sample shown in the screenshot please? Regards Dave.

 

Probably not ripe yet, my onion seeds are still green in the pods (look the same as your leeks)
