A fun sunflower fact is young sunflowers track the sun, also referred to as heliotropism. In a study by Science Magazine, scientists reveal sunflowers have circadian rhythms, which promote this behaviour. A young sunflower’s face follows the sun from sunrise to sunset every day and repeats the cycle until maturity.

As sunflowers reach maturity, their internal clocks start slowing down until they finish the heliotropism behaviour completely. Then sunflowers face east, this allows them to attract up to five times more pollinators because they warm up faster than westward facing plants. ~ proflowers
