I look like wheat. Animals and humans don't eat me. What could I be?

I have been driving past this field every day and scratching my head wondering what crop the unusually tall wheat-like grass could be. Last week the crop was harvested and over the weekend it was baled.Today I grabbed the farmer who informed me that it is more profitable than wheat or corn (which he has abandoned altogether) as it requires no special care or chemical treatments and the price is stable. MISCANTHUS grown for bio fuel. Look it up.
