Sunflower name is derived from Greek words helios meaning “Sun” and anthos meaning ‘‘flower”.They belong to the Asteraceae family and are native to North America, although they are now cultivated globally for their ornamental beauty, seeds, and oil. We are going to explore different types of sunflower as we move ahead.
Sunflowers are named for their tendency to turn their heads to face the sun as it moves across the sky, a behavior known as heliotropism. This characteristic trait is most pronounced in young sunflower buds and decreases as the flower matures. While this heliotropic behavior typically ceases once the flower reaches maturity, the term “sunflower” persists due to its historical association. Although heliotropism occurs due to accumulation of growth hormones when exposed to sunlight. That’s Why once a sunflower reaches its maturity heliotropism is not evident.
The central disk of the sunflower is composed of numerous small flowers called florets, surrounded by colorful petals known as ray florets. These florets are arranged in intricate spiral patterns, contributing to the sunflower’s distinctive appearance.
