What are the plants that predict the weather?

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".

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.

There is a "temperature grass" in southern Sweden, which can measure the temperature like a thermometer.

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.

A strange tree next to 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.
