This is a time lapse video of a dwarf sunflower growing from seed to full flower, then wilting. A version with a beautiful musical score can be found at https://www.youtube.com/watch?v=dKo5IvvtnWw

Unfortunately the flower was too heavy and it collapsed the plant at some point.
This video also illustrates the centripetal anthesis present in sunflowers, where the outer flowers mature first and the maturation process extends inwards.
I would have attempted to get it to go to seed, but these sunflowers tend to be self-infertile.
Video took about 130 days from start to finish. That means it's slightly more than 1 second of video per day of growth.
