Sunflower is a herbaceous plant that is over a year old. Originally from North America, it is now widely cultivated around the world. Its large and bright flowers make it a symbol of summer, with its beautiful yellow or gold color shining in the sun.
Sunflowers are warm and drought-resistant, with an extremely high seed oil content. The oil is flavorful and delicious and can be fried or used as a cooking oil, making it an important crop. The sunflower period can last for more than two weeks.
Sunflowers have high requirements for light and should be grown in a suitable environment. If there is insufficient light, the sunflower will not be able to bloom. However, sunflowers have good drought tolerance due to the sponge-like substances in their stems that can retain moisture.
Sunflowers are not only grown naturally in the wild but are also widely planted in cities for urban greening and beautification. In some places, people also use sunflowers and leaves to create various artistic decorations, such as flower rings and baskets.
In terms of agriculture, sunflowers are an important green fertilizer crop that can penetrate the soil, improve soil structure and nutrients, and increase soil fertility. Sunflowers are also beneficial for bee breeding, as their nectar and pollen are the main sources of food for bees.
One of the interesting phenomena of sunflowers is that they turn towards the sun. From germination to blooming, their leaves and flowers will turn from east to west with the sun. However, after the flowers are in full bloom, they will no longer rotate and will remain fixed, facing east.
The reason why sunflower leaves and flowers rotate towards the sun is that sunlight stimulates the elongation of the backlight cells, causing them to turn towards the sun. When the sun sets, growth is redistributed, and the sunflower slowly turns back to its starting position, which is the east.
After the flower plate is in full bloom, the sunflower also stops growing and fixes the flower plate towards the east. This may be the result of natural selection, which is beneficial to the reproduction of sunflowers.
Sunflowers represent a positive spirit and vitality and are often used as symbols in literature and art. In literary works, sunflowers represent hope and strength, while in painting and photography, they are used as a composition element.
The flower language of sunflowers is belief, glory, pride, loyalty, and admiration. Sunflowers represent the brave pursuit of happiness, with their loyal flowers always facing the sun, just like absolute loyalty to a belief.
Finally, it is essential to note that although sunflowers are beautiful, they can cause potential harm. Their pollen can cause allergic symptoms and should be taken into account. Additionally, when planting sunflowers, it is essential to avoid planting them in excessively fertile soil as this may lead to high stems, poor wind resistance, and easy breakage.
Sunflowers are beautiful and significant plants that are cultivated worldwide. Their positive spirit, vitality, and loyal flowers make them a symbol of hope, strength, and admiration. However, it is crucial to be aware of their potential hazards and take precautions when necessary.
