Sunflowers are not classified as day-neutral plants; they are generally considered to be photoperiod-sensitive. They typically require long days to flower, thriving in environments with ample sunlight. However, some varieties have been bred to flower under a range of day lengths. Overall, the traditional sunflower (Helianthus annuus) tends to prefer longer daylight hours for optimal growth and blooming.
