I have noticed that wheat grows beneath the boughs of roadside trees here in the UK. It must have come from birds eating an ear of corn and spilling half it's contents. The same may well be happening with sunflower seeds below utility poles beside your highways.
Kansas, Minnesota, North and South Dakota are the chiefs in growing sunflowers. They also grow near highways because of the types of air they need. They all grow either in tropical grassland, forests, or everyday gardens.
The basics of it is that sunflower seeds get dropped all the time but usually land on hard ground and never make it under the soil. By highways and dirt roads and the edge of planted crop fields the soil gets turned over quite often, therefore putting the seed in the ground.
