Here are some interesting facts about these wonderful plants!
1.Young Sunflowers Follow the Sun
Young sunflowers show a behaviour called heliotropism. Sunflower buds and young flowers will face east in the morning and track the sun throughout the day. They have their own biological clocks which helps them to follow the sun and then move back to their original position at night and repeats the cycle until maturity. They face east when fully grown as this attracts many pollinators especially bees.
2.They Made up of Thousands of Small Flowers
You might believes each sunflower is only a single flower, but each sunflower is actually made up of thousands (up to two thousand) of small flowers. These small flowers are filled with nectar making them a great treat for bees too.
3.The Tallest Sunflower Was Over 30 Feet in Height
On average, sunflowers reach a height of between 6 to 10 feet, but they can get really tall. The tallest sunflowers ever recorded was 30 feet, that was growing by Hans-Peter Schiffer in Germany. It was confirmed by Guinnes World Records on August 28, 2014. Schiffer had already broken the record three times before.
"Keep your face to the sunshine and you cannot see the shadow It's what sunflower do."
- Helen Keller
4.Sunflowers Protect Us From Harmful Radiations
Sunflowers are not just glorious flowers but are really good at absorbing toxins and protect us from harmful radiations. Scientists planted millions of sunflowers after the destructive tsunami destroyed reactors in the Fukushima nuclear power plant. Sunflowers can absorb much more of these toxins than other plants that's why they are 'hyperaccumulators'.
5.There Are 70 Different Species of Sunflowers
The popular sunflower is Helianthus Annus. However, there are 70 different species of the Helianthus family. They can be tall while others are short. The shortest sunflowers usually grow in clusters and are called dwarfs. Most people relate sunflowers with yellow colour, but these flowers come in a variety of colours including red, orange, purple, pink and white
6.They Are Native to North America
Sunflowers were first grow in North America over 5000 years ago. North Dakota is recognized as the popular U.S State for sunflower production by a University of Missouri journal.
"Sunflowers end up facing the sun, but they go through a lot of dirt to find their way there."
