Can plants predict the weather?

Willow leaves in summer, which droop and sway with the wind, are a kind of scenery. But if the willow leaves turn white, it indicates that rainy weather is coming. In fact, if you look closely, you will find that it is not the willow leaves that turn white, but that they will turn upside down before the rainy day comes, because the reverse side of the willow leaves is light green and the surface is covered with a layer of "white frost", so it looks like the willow leaves turn white.

Pumpkin vine

Usually, the top of the pumpkin vine grows slowly downward, but if the top of the pumpkin vine is generally upward in summer morning, it indicates that the weather will turn from sunny to rainy. On the contrary, if the top of the pumpkin vine is generally downward in rainy weather, it indicates that the weather will be fine.

Artemisia selengensis

Artemisia scoparia is a drought-tolerant wild plant of Compositae, which is distributed all over China. If it is found that many tender buds are born at its roots in dry weather, it indicates that it will rain soon.

Green bar tree

In Dinglong Village, Xincheng County, Guangxi, China, there is a green bar tree that is over 100 years old. Its leaf color changes with the weather: on sunny days, the leaves are dark green; After a long drought, the leaves turn red; When the weather cleared up after the rain, the leaves returned to their original dark green. Local residents can know whether it is cloudy or sunny according to the color change of leaves, so people call it "meteorological tree".

Mimosa pudica

Mimosa is wonderful: if you touch it, its leaves meet and hang down like shyness. Among them, due to the different degree of shyness, the weather is different: if the touched mimosa leaves close and droop quickly, it will take a long time to recover, which means that Wan Li is clear and sunny; On the contrary, the leaves contract slowly after being touched, droop slowly, or open slightly, indicating that the wind and rain are coming.

four o'clock

Mirabilis jalapa, also known as rouge flower, blooms in summer and has many colors such as purple, red and white. It usually blooms the night before 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. So when forecasting the weather, it is not only clouds that can tell the weather. Maybe small animals know the weather. Even these plants can tell whether the weather is good or bad.
