Last summer I was driving cross country from the east coast to the west coast and I was somewhere in Kansas around noontime. For miles, I am surrounded by farms that are raising a single crop. It’s beautiful to look at but confusing to understand.
When I look to my right, I see fields of yellow. When I look to my left, I see fields of green. And yet, a single crop is being grown.
Explain please.

They’re sunflowers and the face the sun so one side is facing away from you and the other is facing you.
You are correct, Riddl.
At noontime in the Northern Hemisphere, the sun is not overhead, it’s in the south. What I’m seeing is Heliotropism. That’s the tendency for flowers to turn and face the sun. The plants on the left side of the road are turned away from me and facing the sun. And the plants on the right are turned toward me and facing the sun, and the crop is sunflowers. So when I look to my right, I see the yellow flower. When I look to the left, I see the green backs of the sunflowers.
You are today’s winner.
