On Louisville Road on the way to Deerfield you pass five open fields that can give unsuspecting drivers a start. The fields are full of canola blooms.
Canola is a new crop for East Tennessee with more and more of the yellow fields appearing each year. You certainly don't mistake the fields for soybeans or switchgrass. North Dakota once produced almost all the canola oil in the United States, but folks in the south are getting in on the act. Wikipedia says "canola" is short for CANadian Oil, Low Acid.
Whatever the name, van Gogh would have certainly loved the palette.
