- The process of plants tracking the course of the sun is known as heliotropism and can be observed most famously in the sunflower. Dr Mike Haydon, University of Melbourne, explains this magnificent feat of flora.
Where I live, they do not. The summers sun is too hot for their little faces in summer, and they carefully turn their faces away from the sun all day. (GA USA)
We are going to have to remake this video now that they are turning there back on the sun
How do you know they haven't always done that? Didn't the video at the end say once they mature they settle on facing east?
In Spanish sunflowers are called girasoles or “sun spinners” 😮 I did not know why until today
They mostly call them girasoles cuz therye spanish
Sun turners
Although "girar" does mean to spin, it also means to turn, to rotate, to twist, so in this context, it's more of a sun turner (GIRA hacia el SOL = girasol).
Beautiful sunflowers 🌻 ❤
i heard there is a strange phenomena where they are no longer tracking the sun this year
Yes true story. Biblical end times are here.

Why have sunflowers been turning away from the sun?
When is someone going show the time lapse. I know I have seen the video.
That's an interesting explanation of *why* they do it, but the question of *how* they do it - without muscles - wasn't even addressed. I know it seems like an elementary, and therefore silly, question, but precisely how does a sunflower turn? What goes on in the stem to make them turn? *EDIT:* Turns out that, during the day, the east-facing part of the sunflower stem grows more than the west-facing side, which turns the sunflower from east to west - tracking the sun. At night, the reverse happens; the west-facing part of the stem grows more than the east-facing part, which causes the sunflower to turn east to await the rising of the sun.
I was going to ask the same question after watching the short video. Thanks for providing a possible explanation!
Today is July 26, 2024 and sunflowers are turning their backs or faces from whatever the sun is now!
I came here looking for answers to that and at the end of the video they say, “This dance doesn’t last forever . . . once these flowers have matured they will settle on facing east to continue attracting pollinators” and the video I seen today (out of many) the sunflowers were in fact facing east, which was reassuring, but it doesn’t hurt to still keep an out and question everything

Nice
Mine stopped.2 years ago and the last year I planted them they were all deformed, but this was after we had fall out from Palestine train wreck in Ohio.
"Circadian clock" is just a word. It explains nothing.

Nice but question not answered.
Plant consciousness.
@@havefunbesafe I agree that they are conscious.
more conscious than you
They have auxin that's why they move towards sunlight
I don't destroy my brain with virtual games like you.@@xXxTERDMUFFINxXx
Nature spirits co-evolved with all and they guide such activities based on the needs of the plants, animals, insects, earth, water, etc
In persian we literally call then sun worshippers
Is this new sun real
Man cannot create a sun. The sun is probably giving off more radiation since it’s in a new cycle.

Not true. Or at least not anymore.
