A sunflower is a flowering plant that produces flowers that have a similar appearance to the sun.
A sunflower is also known as the common sunflower.
The scientific name for the sunflower is Helianthus annuus.
The sunflower is a member of the Helianthus genus in the Asteraceae family.
The average height of a sunflower is 9.8 feet and the record for the tallest sunflower was 30.1 feet.
The flower of a sunflower plant is heliotropic, which means it can move in response to the sun’s current direction. Only the buds and young flowers move with the sun. As the flower matures and starts to produce seeds it will have a fixed direction, which is typically east.
The disk of a single sunflower contains up to 2,000 tiny flowers. All those tiny brown and yellow fuzzies in the middle of a sunflower disk are tiny flowers, which can make thousands of seeds.
Sunflowers reproduce through pollination, with the support of pollinators, like bees. However, if a sunflower can’t access pollinators it can pollinate itself.
Sunflowers are popular for their beauty and the seeds they produce.
Sunflower seeds have become an important and valuable agricultural crop.
Sunflower seeds are the fruit of a sunflower, which can be eaten or turned into an oil.
