7. Fibonacci sequence.
The number of florets is not random. The spirals formed follow a Fibonacci sequence. The first few numbers of a Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34. Each number (after the first 1) is the sum of the two previous numbers. I haven’t wrapped my mind around how that relates to the spirals, but for the advanced mathematically inclined, here is a video on YouTube.
