Shortly after the flower is spent and starting to dry up some, you should be able to feel the swelling seed pod just below where the bloom is attached to it. I have some that started to develop, and then aborted the process shortly after. After a couple months there should be a large pod already. If not it didn't work.
I would never cross this many blooms on one stem, but Chardonnay And Ice set 4 bee pods on one stem. It could very well be that they are empty though, as many bee pods are. Funny thing is I have tried often to set a pod on it, and failed. I haven't tried in a long time. Maybe next year I will.
