I planted some of these one of them has a flower lower down from the one at the top and has some nodules there. I was wondering if anybody could explain them.

So, some alliums (many? all? I know garlic does it) not only grow from a bulb, but also produce little mini bulbs in the flowerheads instead of (or in addition to? I'm not entirely sure) seeds

It looks like in your plant, one of those bulbils has got the wrong idea, and decided it's time to become full fledged flower stem instead of just a baby bulb.

Sort of the same sort of transient mutation that produces double flowers or four leaf clovers. Plants are flexible, and can have all sorts of strange things happen without it being fatal. Sometimes people even like it and try to cultivate it (though I doubt your particular weirdness is something that can be perpetuated)

Thanks I was wondering if they were seeds. Think this happened because the plant got damaged by the wind when it first started and it just started over. Thanks again for the reply

They aren't seeds per-se. They're clones of the parent plant, but you can plant them like seeds and a new plant should grow. I think, looking at your plant that the bulbils are the yellow things at the bottom and there are also green seed capsules at the top. I would have to look closer to be sure - my experience was with garlic, which looks slightly different, and we haven't grown it in a few years.
