Corn or cane? Both are tall, leafy and green. Sugar cane grew on our paternal grandparents ' Mississippi farm in the 1950s, during my infancy. I had trouble telling them apart by sight. That is one other area, where I never surpassed Daddy. He could look out of a car window, at crops , while driving down the road, and call them by name. That, I still cannot do, and so envy him!
