Time Lapse: Sunflower Following The Sun - Phototropism/Heliotropism

Visit www.jandjacres.net/ for more hobby farm activities.
The bud of a sunflower is heliotropic - meaning it follows the sun. This behavior stops once the flower blooms.
Take a look at this time lapse - a full day of movement in 2 minutes!
One viewer informs me that this is a good example of phototropism!

I kid you not - this is perhaps one of the most beautiful things I have ever seen! I am such a sunflower fan!

[@JandjacresNet]

It is really cool. And hard to capture! Some days it was just way too windy, or the light was hard to watch (flashing between cloudy and full sun, making a strobe like effect on a time lapse). This was the 5th attempt and with more rain coming, and therefore more wind, decided to go with this one :D

I drove by a field of sunflowers that were in bloom. They were facing east and all of their heads were bowed down, as if in reverence. I presumed it was because it was not sunny/approaching the end of the daylight and they were waiting for the sun to rise again. Since you say they do not follow the sun after they bloom, I am wondering why their blooming heads were all bowed in the same direction. It was quite the sight to behold. Thanks for clarification.

Hello. Found this the other day while trying to teach a student about Endocrine theory, and how the "tropism" of a hormone can be understood by the phototropism of a sunflower. For science, this is highly effective. I'd recommend including the word phototropism in the description at least. You'd get even more hits, and for elementary educators, your channel seems like it would be a gold mine of content. Also, read your comment on the Herculean will it took to get this shot, so a creator: Bravo!

[@JandjacresNet]

Thank you for letting me know about the other uses for this video! I'm honored to know it was used as an educational tool :-D Now that we have even better filming equipment I may have to re-shoot this video - next year :-)

[@AldermanFarms]

That is too cool for school, Daddy-o. Enjoyed that.

hearing this song makes me so nostalgic

[@JandjacresNet]

We filmed that with our Plotwatcher Pro trail/game camera. It is a time lapse camera, so nothing fancy on my end. 8GB SD card, but the video takes up a whole lot less than that. I've recorded several days of sunrise to sunset on that card with the camera set to 10 second intervals before it was full. Thank you for watching!

[@JandjacresNet]

It is pretty neat, isn't it :) Thanks so much for watching!

[@catchifyoucan232]

I really like the video! This is my first year growing sunflowers! I have buds that look just like the one in this video, same size! Do you know how long it takes them to open from this point on?

[@HeyKevinYT]

this is cute!

[@NorfolkDownFilms]

Very cool, thanks for sharing

[@amywas1]

I have always been astonished by how different plants appear during the night. Asterids such as Orthosiphon Aristatus can particularly breathtaking on a moonlit night.

[@marcelarodriguez3503]

This is cool!

[@warchief425]

I just looked at my sunflower plants and they are tilting to the west. Pretty cool.....

[@JandjacresNet]

It sure is :) Thanks for watching.

[@davidtrees1714]

Wow, how quick are J...lol... Ok I will see if it is available here. I have a Canon 600d, I think tts called Rebel Tx3 in the USA. Thanks again. I love night photography and time lapse. Cheers David

[@JandjacresNet]

You caught me sitting at my email and YT emails me about new comments :) Feeling a little envious of your camera :) Best of luck!

[@davidtrees1714]

What type kit did you use to do this? How big was the SD card? Nice job J. Thanks for sharing it, David

[@JandjacresNet]

As it mentioned in the text - this is just the bud of the sunflower - before it blooms. You cannot take a video of a sunflower blossom moving, because they do not move once they bloom.

[@sherylmccoy8884]

Just what I need to show participants in my class. It's a team project and free.

[@JandjacresNet]

I hope they enjoyed watching!

[@arrowitgraystun]

That’s sick hell

[@user-xf3yg7kd7v]

V hard work done to make video

[@user-fu7vt4xr9t]

when i decide to love as a sunflower

[@JandjacresNet]

Way off. Probably because the trail camera we use to do this was sitting out in the full sun. It is in a dark camouflage case, which likely heats up all the internal mechanisms, such as the thermometer. It got up to 90F with 52% humidity the day this was shot.

[@robbiepeterh]

I love this video. But even more I love the music! What is it?

[@JandjacresNet]

It is a piece called Bluegrass Interlude, produced by DoverhillMedia which I paid for and downloaded from Pond5.com.

[@robbiepeterh]

Thanks!

[@user-uy7ff6zz5q]

Some saying that some sunflower plants arnt following the sun any more, im here looking .

[@1122kiwi]

cool

[@warchief425]

This was @7:30 pm (tilting west) .....

[@Sheila6325]

That is so amazing! The Lord did some amazing things on this planet. How Beautiful!

[@joshuaburas669]

It's not magic it's science. Merely hormones telling the part of the plant away from the sun to grow faster than the lighted part so it bends towards the light.

[@kevantas5]

@@joshuaburas669 Science put in place by the Creator. What a good God Jesus is. A God of order and science far above human understanding.
