Question:
Hi!My name is Yati.I urgently need to know whether is it true that sunflowers faces the sun in the day?Also,does this mean that it will always face the sun?Thanks for your help!



Replies:
The mechanism is called "heliotropism" or sun-tracking.

During a trip to France in 1998, we noticed that sunflowers growing en masse in a field all were facing east. Since we did not see any others facing elsewhere during the day, I assume they do always face east. I have not seen sunflower fields anywhere else to confirm or dispute this finding, however.
