Read that sunflowers track the sun even on cloudy days, blew my mind
I was looking up why some of my sunflowers were facing different directions last week and stumbled on this fact. Turns out they have a built-in circadian rhythm that makes them follow the light even when you can't see the sun. Found it on a botany site from a university study. I always figured they just liked direct sun but it's way more complex than that. Has anyone else noticed their cut sunflowers moving in the cooler after a day or two?

Ngl I gotta push back on the dog thing. Dogs follow sunbeams because they're warm and comfortable, not because they have some internal light tracker like a plant. Animals move to stay comfy all the time, that's just basic instinct. Sunflowers are actually growing and bending their stems based on light sensing cells, completely different mechanism. Pretty sure your dog is just a lazy creature of habit chasing heat, not doing some complex biological clock thing. Tbh it's kind of a reach to compare a plant's circadian rhythm to a pet shifting position in their sleep.

Caught my old dog napping in a patch of sunbeams that moved across the living room floor one afternoon. She shifted every twenty minutes or so to stay right in the warm spot, totally unconscious of it. Made me wonder if animals have the same kind of internal light tracker. Ever seen your pets follow a sunbeam like that?
