->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 stem of a sunflower can grow up to 3 m (10 ft) tall and the flower head can be 30 cm (11.8 in) wide.->Sunflowers are very fast growing plants, in the right conditions they can grow 8-12 feet (2.4 m - 3.7 m) tall in six months
.->As of 2012, the Guinness World Record for the tallest sunflower is 8.23 m (27 ft) for a sunflower grown in Germany.
->Famous Dutch painter Vincent Van Gogh did a series of paintings featuring and called Sunflowers.
