Characteristics. It takes about 11 days for an annual sunflower seed to germinate and appear through the soil, and roughly 90 days to reach maturity. Sunflowers attain their maximum height in about 50 days, followed by head development and seed production.unflowers are fast growers capable of reaching their maximum height in one season.
