Why do morning glory flowers bloom at four in the morning?

1. Basic Introduction

Normally they enter the growing season in spring and bloom in summer. They come in a variety of colors, mainly including purple, blue, crimson, etc. They are a common ornamental plant and are very beautiful when they bloom, and everyone can enjoy them.

Its fruit also has medicinal value. It has strong adaptability, prefers mild sunlight, and mainly grows in places with lush vegetation.

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 long process of adapting to the environment, they will perceive the world in their own unique way, and then open up in the way they think is appropriate and at the time they think is appropriate, so that everyone can appreciate it.

Generally, it opens at four or five in the morning, and the flowers close around noon.

3. Main reasons

(1) Personal reasons

Its flowers are large and thin, storing more water. In the early morning, the water supply facilitates the flowers to open. At noon, the water is depleted and the cavity naturally becomes closed.

(2) Sunlight

In the early morning, there is no sunlight or the sunlight is weak, which will not have much impact on it and it can bloom smoothly; at noon, the strong sunlight will evaporate the moisture in its body and cause the flower to close. If placed in the shade, it will remain in bloom until the afternoon.

This means that without the support of photosynthesis, it can also bloom in the early morning due to its own periodic movement. This also proves that not all plants need sunlight to bloom.
