Why do morning glory bloom at 4: 00 in the morning?

1. Basic introduction

Usually they will enter the growing period in spring and bloom in summer with a variety of colors, including purple, blue, scarlet and so on. They are a common ornamental plant. They are very beautiful when they bloom, and everyone can enjoy them.

At the same time, its fruit also has medicinal value. It is adaptable, likes mild sunlight, and mainly grows in places where plants are luxuriant.

2. Flowering time

First of all, we should make it clear that the flowering state of plants is mainly determined by their own biological clock. In the process of long-term adaptation to the environment, they will perceive the world in their own way, and then open it in their own way and at the right time for everyone to appreciate.

Normally, it opens at four or five o'clock in the morning, and by about afternoon, the flower closes.

3. The main reasons

(1) self-cause

Its flowers are large and thin, and it stores a lot of water. In the early hours of the morning, it is provided with water to facilitate the opening of the flowers. By noon, when the water runs dry, it will naturally be closed.

(2) the cause of sunshine

In the early hours of the morning, when there is no sun or the sun is weak, it will not have much effect on it, and it can blossom smoothly; at noon, the strong sun will steam off the moisture in its body and close the flowers. If you leave it in the shade, it will blossom until the afternoon.

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