Flowering at night

Although most plants bloom during the day, there are many exceptions, such as evening primrose, which blooms at night.

Evening primrose blooms at night. In fact, it is a habit that has been inherited for a long time. At night, evening primrose will emit bursts of fragrance to attract moths for pollination. This is an adaptation of Noctiluca to the environment.

The petals of nocturnal incense are very unique. It is obviously different from the petals of other plants. There are pores on the petals of nocturnal incense. This pore is characterized by that when the air humidity increases, the pores will open wider. The larger the pores open, the more aromatic oil will evaporate, so the aroma will be particularly strong.

In addition, the flowers of nocturnal incense emit fragrance not only in the evening, but also in rainy days.

Why bloom at night

Why does evening primrose blossom at night? This is actually related to its origin.

Nightingale originally grows in subtropical areas. According to its growth habits, it needs flying insects to help pollinate. However, in subtropical areas, the temperature is very high during the day, and the flying insects rarely move. They will come out to look for food at night. In order to pollinate better, it will bloom at night and emit fragrance to attract flying insects. After a long time of reproduction, it developed the habit of flowering at night.

Evening primrose usually blooms at 8-10 pm, when the temperature is very appropriate.
