The flower that blooms at four o'clock in the afternoon, it is cosmos. It opens at 4 p.m. in autumn and is like a messenger of time, conveying the arrival of autumn to people. Its flowers are shaped like a colored sun, and the color of the petals changes from pale red to deep red and then gradually to white.
The cosmos blooms at 4 p.m. because it needs adequate light and temperature to photosynthesize and maintain normal growth. In autumn, around 4 p.m. is the last time before the sun goes down, when the light and temperature are perfect for cosmos growth. Therefore, the cosmos blooms at this time, making full use of this time for photosynthesis and storing energy for the following winter.
In addition to cosmos, there are many flowers that also have their own blooming times. For example, morning glory blooms in the morning, sunflowers bloom at noon, and evening primrose blooms in the evening. The blooming time of these flowers is naturally selected for better adaptation, growth, and reproduction.
Blooming at 4 p.m., the cosmos not only shows its beauty and charm, but is also a symbol of autumn. Its presence allows people to feel the breath of autumn and the flow of time. When we see the cosmos blooming at four o'clock in the afternoon in autumn, we can't help but think of those good times and memories, and marvel at the magic of nature and the charm of life.
