Sunflowers in the bud stage exhibit heliotropism. At sunrise, the faces of most sunflowers are turned towards the east. Over the course of the day they follow the sun from east to west, while at night they return to an eastward orientation. This motion is performed by motor cells in the pulvinus, a flexible segment of the stem just below the bud. As the bud stage ends, the stem stiffens and the blooming stage is reached.
Sunflowers in their blooming stage lose their heliotropic capacity. The stem becomes "frozen", typically in an eastward orientation.[citation needed] The stem and leaves lose their green color.
The wild sunflower typically does not turn toward the sun; its flowering heads may face many directions when mature. However, the leaves typically exhibit some heliotropism

How does the Sunflower track the sun?
No-one really knows the exact mechanism for 'heliotropism' -or sun tracking.It appears that an external factor ( the sun) is triggering a not -yet understood factor within the plant.It is still being researched. Heliotropism is the term used to describe the tracking of the sun by the flower buds of sunflowers. Other plants also have flowers and/or leaves that track the sun. First, let's discuss how the plants are able to track the sun. There is a collection of specialized cells at the base of the flower bud or leaf called a pulvinus that carry the "motor" cells that enable the plant leaf or flower to track the sun. These cells enlarge or shrink according the turgor pressure from the water inside them. In response to blue wavelength light, potassium ion concentration increases in the "motor" cells on the shadow side of the pulvinus. With the increase of potassium ions the osmotic potential in the cells becomes more negative and the cells absorb more water and elongate, turning the face of the flower to the sun.
