Flower petals are rarely a different quantity than a Fibonacci number. Look it up. It's pretty amazing. However, for a sunflower, that number should be 34, 55 or 89 depending upon its size.

The sunflower (Helianthus annuus) is a flowering annual dicot. As a dicot, its petals are in lots of 4 or 5. There are two types of petals on a sunflower. First there is the small disc florets in the center that form the seeds. These are very simple flowers with a single circlet of unassuming petals. The outer petal-bearing or ray florets are sterile and they contain the color petals. Numbers differ between varieties, but they will be in multiples of either 4 or 5.
