The sunflower is a large inflorescence, this means the flower head is actually made of many tiny flowers called florets. Central florets look like the center of a normal flower while the outer florets look like yellow petals and together they make up a "false flower". This natural design helps insects and birds to easily see the sunflower and after pollination every little flower or floret produces a seed.
The flowers within a sunflower head are clustered in a spiral pattern whereby each floret is oriented towards the next by the golden angle of 137.5. This produces a pattern of interconnecting spirals. The number of left and right spirals are consecutive Fibonacci numbers. Normally there are 34 spirals in one direction and 55 in the other. Very large sunflowers can have 89 in one direction and 144 in the other.
There are two kinds of sunflower seeds. Sunflower oil which is used in cooking and in margarines is made from black seeds and snack food is made from the striped seeds. The seeds can also be used as bird feed.
