Time Lapse of Sunflower from Seed to Flower

This is a time lapse video of a dwarf sunflower growing from seed to full flower, then wilting. 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. Providing time lapse videos which illustrate concepts in plant sciences.
