Ideal for spring and summer production with two-three overlapping rows of classic orange petals surrounding a dark disk. Single Stem. Many sunflowers are bred to be male sterile, or pollen-free, to help foster the nice clean appearance of flower heads that wholesalers and florists have come to demand. Nothing expresses the essence of summer better than a bunch of bright cheery clean sunflowers! Single stem varieties are best for high density plantings to produce tall stems. Color: Deep orange with dark disk
