|Three petals are more common.
|There are hundreds of species, both wild and cultivated, with five petals.
|Eight-petalled flowers are not so common as five-petalled, but there are quite a number of well-known species with eight.
|twenty-one and thirty-four petals are also quite common. The outer ring of ray florets in the daisy family illustrate the Fibonacci sequence extremely well. Daisies with 13, 21, 34, 55 or 89 petals are quite common.
