The Fibonacci Numbers in Flower
« on: November 17, 2012, 01:44:46 PM »
Did you know, for instance, that most daisies have 34, 55 or 89 petals? Those numbers should be familiar to you; they are the 9th, 10th, and 11th Fibonacci Numbers. Have you ever wondered why four-leaf clovers are so rare? It's because four isn't a Fibonacci Number. Here is a list of flowers with number of petals:

Number of Petals                         Flower
3 petals (or 2 sets of 3)                 lily (usually in 2 sets of 3 for 6 total), iris
5 petals                                         buttercup, wild rose, larkspur, columbine (aquilegia), vinca
8 petals                                        delphinium, coreopsis
13 petals                                        ragwort, marigold, cineraria
21 petals                                        aster, black-eyed susan, chicory
34 petals                                        plantain, daisy, pyrethrum
55 petals                                       daisy, the asteraceae family
89 petals                                       daisy, the asteraceae family

    There are exceptions to this list. Most fall into two categories; a doubling of the number of petals, and/or a version of the Fibonacci Series called the Lucas Series (2, 1, 3, 4, 7, 11, 18, 29, 47, 76, etc.). Mutations and variations from species to species also account for exceptions but when the number of petals are averaged, the number will usually be a Fibonacci or Lucas Number.
