Though sunflowers look like one giant flower, they’re made up of thousands of tiny flowers. The big yellow petals protect the little flowers in the middle when the plant is growing. Look closely and you’ll see that the tiny flowers make a groovy spiral pattern.
In summer, sunflowers grow fast and they can grow very tall. The world record for the tallest sunflower is over 8 metres – as tall as a small tree! Why not see if you can grow a record-breaking sunflower?
