black-eyed susan contains 13 petals,

sasha daisy contains 21 petals, field

daisies contains 34, and other types of Fibonacci Spirals on

daisies contain 55, and 89 petals. Pineapple

Pineapple spirals formed by their

hexagonal nubs. The nubs on many

pineapples form 5 spirals and 8 spirals, or 8

spirals and 13 spirals that rotate diagonally

upward to the right depending on the size of

the pineapple. The numbers 5, 8, and 13 are

Fibonacci numbers.
