Novel green and purple sunflower.
Often, sunflower backs can be just as beautiful and interesting as the faces. To bring the "sunflower back" look to the forefront, American sunflower breeder Tom Heaton bred two innovative varieties (Sun-Fill Green and Sun-Fill Purple) with highly ornamental sepals that wrap the flower face, creating that look typically only found on the back of the flower.
