Starting from a seed, a sunflower plant grows, flowers...and then wilts. I've always thought these kinds of videos were wonderful, but given recent events, they are hitting with an extra poignance. Or maybe hope in a strange sort of way? I don't know what one is supposed to be feeling about anything these days.
In this other sunflower time lapse, you can more clearly see the little seed helmets worn by the tiny plants soon after sprouting. Cute!
