The association of Fibonacci numbers and plants is extremely well seen in the daisy. Notice the Golden Spirals.

Ordinary field daisies have 34 petals ... a fact to be taken in consideration when playing "she loves me, she loves me not". In saying that daisies have 34 petals, one is generalizing about the species - but any individual member of the species may deviate from this general pattern. There is more likelihood of a possible under development than over-development, so that 33 is more common than 35.
