Scientific Facts About Sunflowers
1. The sunflower is called “sunflower” because of its characteristic behavior of tracking the movement of the sun throughout the day. The flower head of the sunflower follows the sun’s path from east to west, facing eastward in the morning and gradually turning westward as the day progresses. This phenomenon is known as heliotropism. The name “sunflower” captures this unique characteristic and has become the common name for this plant.
2. The sunflower belongs to the genus Helianthus, which is derived from the Greek words “helios” meaning “sun” and “anthos” meaning “flower.” This further emphasizes the connection between the sunflower and its association with the sun.
3. As sunflowers grow older, they tend to stay facing east to get the most sunlight possible. So while young sunflowers can track the sun, older ones decide it’s best to keep their faces fixed towards the east for maximum sun exposure. It’s like they know the sun’s secrets!
4. The sunflower is more than just a single flower. When you look at a sunflower head, you’re actually observing a collection of numerous individual flowers. This unique formation is known as an inflorescence, specifically a composite flower.
5. The outer perimeter of the sunflower head consists of large, colorful petals known as ray florets. The central part of the flower, called the disc, is composed of hundreds or even thousands of tiny individual flowers known as disk florets. These florets collectively create the iconic “face” of the sunflower.
6. The central florets of the sunflower are hermaphroditic, meaning they have both male and female parts for reproduction. That means they can self-pollinate if they need to. But cross-pollination by bees, butterflies, and other pollinators is more common since these central florets are filled with sweet insect-attracting nectar.
7. Sunflowers have a secret defense system. If you take a closer look, you’ll spot tiny brush-like structures called trichomes on sunflower’s stems, leaves, and bracts (leaf-like structures below the flower head). These fine hairs serve as defense mechanisms, keeping pests at bay and helping to reduce water loss.
8. Sunflower seeds are developed from the disc florets situated at the center of the sunflower head. After these florets get pollinated, the ovary inside them undergoes fertilization and transforms into a seed. As the sunflower head ripens, those disc florets dry up, and the seeds inside them become fully grown and ready.
9. The arrangements of the florets in the sunflower head often follow a mathematical pattern known as Fibonacci numbers. The number of spirals in one direction is typically a Fibonacci number, and the number of spirals in the opposite direction is usually a consecutive Fibonacci number.
10. Below the surface, sunflowers have a robust and extensive root system. Their taproots can reach several feet deep, helping the plant anchor securely in the ground and absorb water and nutrients from the soil.
11. Sunflowers have been grown in space as part of scientific experiments. In 2012, sunflower seeds were sent to the International Space Station (ISS) as part of the educational initiative known as the “Tomatosphere” project. The purpose of this project was to study the effects of microgravity on plant growth and development.
12. Sunflowers have been used in phytoremediation projects to clean up contaminated soil. They are capable of absorbing heavy metals and toxins from the soil.
13. Sunflowers are capable of cleaning up radioactive water. For example, Phytotech, a company in New Jersey that specializes in using plants to clean up pollution, was using sunflowers to clean up radioactive water from Chernobyl. They placed the sunflowers on floating rafts in the water, so the roots of the sunflowers absorb harmful cesium 137 and strontium 90. Once the sunflowers had absorbed these substances, they were safely disposed of as radioactive waste.
14. In 2015, a sunflower grown in Germany broke the Guinness World Record for the tallest sunflower, measuring a towering height of 30 feet and 1 inch (9.17 meters).
