Do All Flowers Have an Odd Number of Petals?

Good question!

You'd expect symmetry in nature, but as you've obviously spotted, most flowers have an odd number of petals.

If you play he loves me he loves me not with a plant that has an even number of petals, you'll always end on 'he loves me not' (or she loves me not!). But if you choose a flower with an odd number of petals, you'll always land on 'he loves me'….

So here's a quick guide to picking the right flower:

Buttercups and roses = 5 petals

Marigolds = 13 petals

Daisies = 55 petals

But beware - some daisies have 34 (he loves me not! Sob!)

So why do most flowers have an odd number of petals?

It's all to do with something called the Fibonacci series of numbers, which are:

0, 1, 1, 2, 3, 5, 8, 13, ... to work out the next number, just add the last two numbers together. So the next number will be 21 (8+13= 21). If you look at the numbers in our flower guide they were 5, 13, 34 and 55 - all Fibonacci numbers! Nature is full of examples of Fibonacci's big idea. Cut a banana into slices, you'll see there are 3 sections. Apples have 5 .

Can YOU find other Fibonacci numbers in nature?
