I was just looking at my potted poached egg plants flowers and they all seem to be dying off a little, losing their flowers. I would like to collect some seeds to plant and grow next year but i am unsure where the seeds are, are they the petals? Or are they the 4 small ball things that are left in the flower head once the petals have dropped? Or... Are they actually inside these 4 ball thingies? Any help would be great thanks!
