I've noticed that when you travel in other states and you order corn on the cob, it's different. Here we call it sugar corn. It's bicolor and so delicious! I've been places where the corn is all white.
The corn I grow here in CA, is green chopped for dairy feed. All dairy feed corn, that I seen, the kernels are yellow and being green chopped around 110 days, about 15 days before full maturity, that's when it has the best feed quality for cows.
