Why Sunflowers Always Face the Sun and When They Stop

Sunflowers are among the world's most recognisable plants, admired for their towering stems and bright yellow petals that resemble the sun itself. One of their most fascinating traits is their apparent ability to follow the sun across the sky. This movement has inspired myths, artwork and scientific curiosity for centuries. However, the story is more complex than many people realise. Sunflowers do not spend their entire lives turning towards the sun. In fact, this remarkable behaviour occurs only during a specific stage of their growth. Understanding why sunflowers face the sun, and when they stop, reveals an extraordinary example of nature's efficiency and adaptation.
