The Common Sunflower (Helianthus annuus) is a tall, fast-growing annual with broad, hairy leaves. In summer, it produces enormous flowers, up to 12 in. (30 cm) in diameter, with yellow petals and a dark chocolate-colored central disk.

Helianthus annuus or common sunflower is famous for its large and vividly yellow petals surrounding the seeds. The seed heads of the sunflower are arranged in a spiraling pattern connected to the golden ratio and Fibonacci sequence. This characteristic enables the seeds to be placed at a specific angle resulting in optimized packing.

The common sunflower is recognizable for its bright flower on a very tall stem. It is often grown in gardens. These flowers have been important in culture: they were worshipped by the ancient Inca people, and today, they represent eco-friendly movements. The artist Vincent van Gogh made a famous series of paintings about common sunflower. Wild versions of the plant branch out to many flower heads, but domesticated plants typically only have one.

Sunflowers use both Pollination methods. Mainly performed by bees, as well as butterflies, moths, and beetles. When searching for nectar, the bees get covered in pollen, which they transfer to other sunflowers. This activates pollination.
