(522 posts)I'll find out the answer. It may take a few months, I'll watch the neighbors sunflowers when they bloom. I'm in Montana and we won't see sunflower blooms until July or August.
Stay tuned.

(522 posts)So I googled a few phrases and eventually found this.
"Facing east at sunrise, the sunflowers head follows the sun across the sky to face west at sunset. This heliotropic movement, called nutation, results from a bending of the stem toward the sunlight; there is asymmetric growth on the shaded side, causing the flowers to be in a position facing toward the sun. Growth is equalized during the night, the stem slowly straightens out and by dawn is facing east again. On a cloudy overcast day, the sunflower remains facing eastward, awaiting the next clear sunrise. The leaves of the sunflower are also heliotropic. If they are removed, the sunflower head would be unable to follow the sun.
I love nature and how science can explain our world.
