Popcorn flowers

I was surprised to see the head of the survived popcorn was yellow in color this morning. It has finally got flowers. Precisely speaking, the yellow things are not flowers but pollen, and the petal is too small and thin to be observed by the naked eye. It's really interesting to watch how it grows everyday. I'm now expecting to see how it grows into ear of corn, but I'm wondering whether it happens without another popcorn because most plants need mating. All I can do is watering everyday and watching it with love.
