They are sunflowers. And…. based upon their height, leaves, and direction of the sunflower heads as well as the shadow from the woman’s skirt on her legs, and the shadow of the boy’s shorts, I would say that picture was taken at a latitude of N35 deg or lower at about 2 pm in late August to early September with the photographer standing on the north side of the East-West planted field.
