1. Introduction
Sunflowers are hailed as "beauty under the bright sun," and their characteristics and appearance are widely loved and admired. As a widely cultivated ornamental flower and edible crop, sunflowers bring beauty and harvest to people. This article will introduce the characteristics and appearance of sunflowers.
2. Features
The most distinctive feature of the sunflower is its heliotropism. Sunflowers turn towards the sun from morning until sunset. This is because the sunflower's stems and leaves grow very quickly, constantly growing towards the sunlight. At the same time, phytochemicals allow the stems and leaves to change their firmness, enabling the flower to adjust its position at any time. In addition, the sunflower's flower head is another characteristic; it serves as an excellent "hummingbird platform," attracting a wide variety of birds to eat nectar, while also attracting numerous bees, butterflies, and other insects for pollination.
3. Description of appearance
Sunflowers are very beautiful, with tall flower stalks and umbrella-shaped inflorescences. The inflorescence is composed of many petals, which are deep yellow and dark brown. Because the petals are arranged in concentric circles, the inflorescence resembles radiating rays of sunlight, leaving a striking impression. The sunflower's flower head is also large; some varieties can even have a diameter of over 60 centimeters, making one involuntarily think of a real sun.
4. Conclusion
As can be seen from the above characteristics and appearance, the sunflower is a very unique and beautiful flower, holding an important place in the hearts of countless people. Among the many seemingly insignificant creatures in this world, the sunflower has become a "darling" of people's hearts because of its extraordinary characteristics and unique appearance. We should cherish these beautiful things even more and pay attention to their protection and maintenance in our daily lives.
