Noticing these flowers while sitting on the patio at TAF I began to wonder why the heck they looked as though their backs were facing me. It was 4 o'clock in the afternoon and the sun had moved far to the west yet their faces were still pointing east. I had thought all flowers tracked the sun but I was mistaken - mostly.
After researching the topic I discovered they were "heliotropic" (help us QGG to understand that word would you please) for a short time during their growth. That is to say, they do track the sun UNTIL they become mature at which time the faces are locked east.
So, the next time you plant sunflowers be sure to keep this in mind if you desire to study the faces rather than the behinds of these beautiful plants.

Hummm, so we have to move off the patio and head out into the yard to see the sunny, bright faces of these flowers regardless of the time of day. Who would have ever known this? Certainly not me, atleast until now.
