Flowers are in full bloom, competing to open, fragrant and charming. If we look closely, we will find that different flowers bloom at different times of the day. At four o'clock in the morning, the morning glory blew the purple trumpet; Around five o'clock, the gorgeous roses opened their smiling faces; At seven o'clock, the water lily woke up from a dream; Around noon 12 o'clock, afternoon flowers are in full bloom; At three o'clock in the afternoon, marigold is in full bloom; At six o'clock in the evening, Mirabilis jalapa woke up; Moonlight flowers spread their petals around seven o'clock; Evening primrose blooms at eight o'clock in the evening; Epiphyllum is smiling around nine o'clock. ...
Why do different plants bloom at different times? It turns out that the flowering time of plants is closely related to temperature, humidity and light. For example, the petals of epiphyllum are big and delicate. During the day, the sun is strong, the temperature is high and the air is dry. If it blooms in the daytime, it is in danger of being burned. The temperature in the middle of the night is too low for flowering. After a long time, I have adapted to the temperature and humidity around 9 pm. At that time, it quietly bloomed elegant buds and showed people beautiful smiling faces. Other flowers need insects to spread pollen to seed, and the flowering time often coincides with the activity time of insects.
A botanist once deliberately planted flowers that opened at different times together and built the garden like a clock face to form a "clock" of flowers. These flowers bloom in succession within 24 hours. You only need to look at what flowers have just bloomed to know what time it is. Isn't that interesting?
