Everyone should be fairly familiar with it, because its shape closely resembles a trumpet, so it is also called the trumpet flower. It generally grows along walls, but its blooming time is in the early morning, so do you know why?

1. Basic introduction

Normally they enter their growing period in spring and bloom in summer, in a wide variety of colors, mainly including: purple, blue, crimson, etc. It is a common ornamental plant, very beautiful when in bloom, and everyone can enjoy it.

At the same time, its fruit also has medicinal value. It has strong adaptability, likes mild sunlight, and mainly grows in places with lush vegetation.

2. Blooming time

First, we should make clear that a plant's blooming state is mainly determined by its own biological clock. Through long-term adaptation to the environment, they use their own unique ways to perceive this world, and then open in the way they consider suitable and at the time they consider appropriate, for everyone to admire.

Under normal circumstances, it opens at four or five in the early morning, and by around afternoon, the flower closes.

3. Main reasons

(1) Its own reasons

Its flowers are large and thin, storing relatively more water. In the early morning, with the supply of water, it is easy for the flower to open. By noon, when the water is used up, it will naturally show a closed state.

(2) Sunlight reasons

In the early morning, there is no sunlight or the sunlight is weak, so it does not have much effect on it, and it can bloom smoothly; at noon, the strong sunlight evaporates the water in its body, causing the flower to close. If it is placed in a shady spot, the blooming state can last until the afternoon.

That is to say, without the support of photosynthesis, it can still bloom in the early morning because of its own periodic movement, which also proves that not all plants need sunlight to bloom.
