I hope someone here can help me to understand what I am looking at.

So I was driving through the western part of Kansas and saw patchworks of corn stalks, about thigh to waste high with bright red bunches of seeds on its top. I have never seen corn like this, so I am trying to understand what I am looking at. Is it a color the top has during a maturing process of corn or is it a particular type of corn. searching online gave me the idea that it might be Broom Corn, but this was very short stalks, not talk and was everywhere in fields all over Kansas so I can't believe there is a need for that much Broom corn, but then again what do I know.

I'm very curious.
