Kelsae Onions with bulbils

Last year after returning from working in India I returned to my plot to harvest the Kelsaes which had been left to their own devices for over 3 months. They hadn't achieved any great size and most were around the 1lb mark, but one was almost 2lbs. I held this onion back and later placed the bulb into a large pot to see if I'd be successful in getting any seeds. Well soon the onion started to throw leaves and the bulb began to split it eventually threw up flower spikes from each of the split bulbs. These have been largely left to their own devices and have been outside in all weathers, until recently when I noticed in addition to the flower/seed heads there were small bulbils developing from the bottom of the flower head. When large enough I have removed the bulbils and potted them up.

I believe they should be a clone of the parent and as they are growing now will be two months ahead of my onion seed I normally sow in December. If my assumption is correct I could have some very big onions next year!
