This series of sunflowers differs from the main Sunrich series in terms of timing and height. With maturity days at around 50-65 days, the Sunrich Summer Sunflower varieties fall right in between the Premier (45-55) and Sunrich (55-70) series. Flower shape and color are similar to Sunrich. Now both series can be sown at the same time, allowing you to harvest the Sunrich Summer's first, followed by the Sunrich varieties 1-2 weeks later.
