Quick Answer: Do Sunflower Faces Follow The Sun?

The fascinating phenomenon of flowers following the sun across the sky is called heliotropism.

Why does the sunflower always face the sun?

Facing of sunflower towards the sun is known as phototropic movement. This is due to presence of auxin, a growth harmone in the stem. When the stem tip receives unilateral light, the concentration of auxin increases in the shaded side.

Heliotropism. Sunflowers turn their faces toward the sun as they track it across the sky — an activity known as heliotropism, or solar tracking. Special motor cells at the bases of the flower buds shrink or enlarge as they absorb water, which moves their faces toward the sun.

What flowers follow the sun?
