The video shows a close-up of a green sunflower bud against a black background. The bud begins to open slightly, revealing hints of yellow at the center. As the opening continues, more yellow becomes visible, and the green petals start to part. The yellow at the center of the bud becomes more pronounced, and the petals continue to separate. The yellow area at the center of the bud grows larger, and the green petals are further apart. The yellow color at the center of the bud becomes more vivid, and the petals are almost fully open.
