Which plants can report the weather forecast

Mirabilis jalapa, pansy, meteorological tree, rain flower, pumpkin vine.

First, Mirabilis jalapa:

It usually blooms the first night and withers the next morning. According to the time when the flowers wither, we can judge the weather of the day: if the flowers wither at first light, it means it is sunny that day; If the flowers wither later, it indicates that it will rain that day.

Second, pansy:

A common wild flower variety in Europe, whose leaves can measure the temperature like a thermometer, is called "warm grass". Its leaves are extremely sensitive to temperature. When the temperature is above 20℃, the leaves extend obliquely upward. If the temperature drops to 15℃, the blade will move down slowly until it is parallel to the ground.

When the temperature drops to 10℃, the blades extend obliquely downward; If the temperature rises, the leaves will return to their original state. People can know the temperature according to the spreading direction of its leaves.

Third, the meteorological tree:

Sensitive to climatic conditions, because the proportion of chlorophyll and anthocyanin contained in plant leaves has changed. Under normal circumstances, the chlorophyll content in leaves is dominant, so it is dark green.

After a long drought, there is usually a period of strong light and sultry weather before it rains. In this environment, the synthesis of chlorophyll in Cyclobalanopsis glauca leaves, which is very sensitive to climate change, was inhibited, while the synthesis of anthocyanins was accelerated and dominated in the leaves, so the leaves changed from green to red.

Fourth, wind and rain:

That is the red calamus lotus. Whenever the wind and rain come, it will be full of energy and in bud. When the storm comes, it will open quickly, and it is still graceful despite the storm; After the storm, the color is gorgeous, and the bonus is like the sunset, reflecting the mountain cliffs. The local Dai people call it a flower that blooms in the face of ups and downs, and the Dai language calls it "the exotic flower of waxy butterflies".

Five, pumpkin vines:

In summer morning, the top of pumpkin vine is generally upward, which indicates that the weather will turn from sunny to rainy. However, if the top of pumpkin vines is generally facing down on rainy days, it indicates that the weather will clear up.
