Why does tuberose bloom at night?

Flowers at night

Although most plants bloom during the day, there are many exceptions, such as tuberose, which is a plant that blooms at night.

Tuberose blooms at night, which is actually a habit that has been passed down for a long time. At night, tuberose will emit bursts of fragrance to attract moths for pollination. This is a way for tuberose to adapt to the environment.

The petals of tuberose are very unique and are significantly different from the petals of other plants. There are stomata on the petals of tuberose. A characteristic of these stomata is that when the air humidity increases, the stomata will open wider. The wider the pores are, the more essential oils will evaporate, so the fragrance will be particularly strong.

In addition, the flowers of tuberose not only emit fragrance at night, but also on rainy days.

Why do flowers bloom at night?

Why does tuberose bloom at night? This actually has something to do with its place of origin.

Tuberose originally grows in subtropical regions. According to its growth habits, it needs flying insects to help with pollination. However, in subtropical areas, the daytime temperature is very high and flying insects rarely move around, coming out to forage for food at night. In order to better pollinate, it blooms at night and emits fragrance to attract flying insects. After a long period of reproduction, it has developed the habit of blooming at night.

Tuberose usually blooms between 8 and 10 o'clock in the evening, when the temperature is very suitable.
