Sunflower is a relatively new crop among the world field crops and is unique in several aspects. It is one of a few crops that have their origin in North America. Sunflower is further unique in that it has been bred for distinctly different uses: as an oilseed crop, edible confection, birdseed, and, to a much lesser extent, an ornamental for home gardens and the cut-flower industry. It is grown as an oilseed crop worldwide in temperate and subtropical climates.
