Sunrich Summer Provence F1 sunflowers bloom 1 to 2 weeks earlier than the standard Sunrich series, allowing for an extended harvest period when planted together. This single-stem variety produces tall stems ideal for high-density plantings and features the bright, cheerful appearance sunflowers are known for.
Many sunflowers in this series are bred to be male sterile, resulting in pollen-free flower heads favored by wholesalers and florists for their clean look. While single-stem types produce tall stems, branching varieties yield multiple shorter stems and require more spacing in the field.
