Fibonacci Flowers for Friday

1,1,2,3,5,8,13,21,34....... This series of numbers is known as the Fibonacci sequence. Here, the next number is obtained by adding the previous two numbers. Like, 1+1=2, 2+1=3, 3+2=5,..8+13=21, 13+21=34 and so on . Fibonacci found that this mathematical series is followed extensively in nature.These are some of the Fibonacci flowers. Above is the Passion flower, the perfect example of the Fibonacci series in nature.
The five-petalled Pentas

The Bougainvillea flower with three bracts

The two- petalled Euphorbia milli

The Anthurium

Have a great mathematical day!


  1. Interesting post that had me counting, for the good part of an hour, the number of petals on all and sundry flowers in my garden. Ixora defies Fibonacci! It has four petals!! I knew that Maths could not always be right....or else, why did I lag behind in the subject in school? :))

  2. I don't like to count but this is interesting! Pretty photos... your passion flower made me gasp!!

  3. Very interesting post! lovely flowers

  4. Lotusleaf you are having fun with your love of numbers with us! Never heard of Fibonacci and that is probably why I was never good at maths at school. I always seem to find a different answer(and with good reason too) to the problems posed LOL. Next time am out in the garden I will be counting like Shailaja LOL.

  5. I really love the passion fruit lower Lotus :D

  6. Shailaja: Obviously the Ixora has not heard of the Fibonacci series.
    Kanak: The passionflower vine has climbed on to my neighbour's coconut tree and flowering profusely there!
    Zindagi: Thanks for your visit and comment.
    Islandgal: Those who were not good at math in school have become great enterpreneurs, while those who liked math have become teachers!
    Barry: This passionflower does not have any fruit- it is sterile.

  7. simply beautifully captured shots...lovely!

  8. Flyingstars, welcome and thanks for your encouraging comment.

  9. You've made me do some maths today...interesting! And beautiful flowers, too!
