Expect the same gorgeous blooms you get with the Sunrich series, but blooming 1-2 weeks earlier. That is right! Plant alongside the Sunrich series and achieve a longer harvest from one planting. 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, while the branching types produce multiple shorter stems over the season. These need more spacing in the field.
