What plants can detect rain?

Artemisia annua (mainly Artemisia annua and Artemisia ordosica) 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.

Ligustrum lucidum is an evergreen tree, and its leaves grow with autumn. If there is an abnormality in summer, there are only fallen leaves and few leaves (or long leaves), as if it is going to sleep in winter, it indicates that there will be rainy weather in autumn in the next 2-3 months, that is, as the saying goes: "Privet Ye Quan falls, and there will be showers in autumn."

Purple jasmine, also known as rouge flower, blooms in summer and has three colors: purple, red and white. 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.

There is a wonderful flower growing in Xishuangbanna, China. When the storm comes, a large number of flowers will bloom. According to this feature, people can know the weather changes in advance, so it is called "Rain Flower".

In Australia and New Zealand, there is also a strange flower that can also predict whether the weather is sunny or rainy, so people call it "Rain Flower".

Perennial herbs Zoysia japonica and thatch can also predict the weather. When Zoysia Zoysia appears moldy hairs at the junction of leaves and stems, or when the junction of leaves and stems of thatch bubbles, it means rainy days. Therefore, there is a saying that "Zoysia japonica grows mildew and it will rain"; The proverb "The straw stalks spit, and it will rain tomorrow".

Mimosa in China is a magical plant, which can predict the weather changes. If you touch it with your hand, its leaves will close quickly and open slowly, which means the weather will clear up; If you touch the mimosa, its leaves will shrink slowly, droop slowly, and even open again after a little closing, which indicates that the weather will turn from sunny to cloudy or it will rain soon.

In Dinglong Village, Xincheng County, Guangxi, there is a green bar tree 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"

A strange tree (called "Pu Shu" by the locals) beside Dateng Village in Hexian County, Anhui Province, with a height of 7 meters, a tree circumference of more than 3 meters and a crown area of 100 square meters, is also a veritable "meteorological tree". According to the early and late germination and the density of leaves, we can know the rainfall of that year. For example, Grain Rain germinated before, and the buds were leafy, indicating that there was much rain and frequent floods in that year; If the germination is normal and the leaves are sparsely distributed, it means that the weather is good; If germination is delayed and leaves grow less, it is a year with little rain, and severe drought often occurs.

As far as ordinary plants are concerned.

Willow in summer, willow leaves droop and sway with the wind, which is 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 that the willow leaves turn white, but that they will all turn over before the rainy day. The reverse side of the willow leaves is light green and there is a layer of "white frost" on the surface. Interested parties may wish to observe and verify it before and after the summer and autumn rainy season.

The top of the pumpkin vine usually 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.
