Fun Facts about Corn

Corn has been a popular food for many years.  It is estimated that it was first domesticated (grown as a food source)  around 9000 years ago.  Corn grows on stalks, often planted in rows in a field.  The height of the stalks generally grow to 6 to 8 feet tall, but vary in size from 2-3 feet to 14 -16 feet. The record height grown in New York State was 34 feet in 2010!
