There are many magical plants in nature. They seem to be more prophetic than us humans and can sense the changes in nature. The growth changes of many plants are closely related to climate change. Those colorful and charming flowers, plants and trees not only provide people with beautiful enjoyment, but many plants also have the ability to "predict the unknown". Careful people are good at understanding the changes of seasons and wind and rain from the alternation of flowers blooming and falling, green grass and yellow leaves. This can better guide people's life and production in the era when there are no weather satellites .

There are folk proverbs: "willow trees germinate early, and the temperature in early spring is high", "willow roots grow red beards, and will be dripping with rain in the future". Such weather and agricultural proverbs fully demonstrate the life wisdom of our ancestors. From this weather farmer's proverb, we can see that they have long understood that plants can predict the weather. Based on long-term observation and summary, they found that if the willow trees sprout early in spring, it usually indicates that the spring temperature will rise quickly and the flowers will bloom early. If the willow trees grow 4 to 7 cm long fibrous roots in July and August, it indicates that in the next month, there will be frequent rainfall and the possibility of floods, so flood prevention preparations need to be made.

and mimosa also have the ability to predict weather changes. Everyone knows that Mimosa is an action genius. In fact, Mimosa is also an excellent weather forecaster. In daily life, as long as we touch the mimosa with our hands, their leaves will close immediately, and the petioles will droop, but the speed of opening and restoring is relatively slow. That is what it is telling people that the weather will be fine in the short term. On the contrary, if the leaves cannot close or close slowly but open quickly, or they just close and then open again, it indicates that it is time to turn to rainy weather. Scientists have found that the reason is that the sensitivity and shrinkage of Mimosa leaves are closely related to the air temperature - on sunny days and high temperatures, the leaf pillows shrink quickly and the leaves are easy to close; when the air humidity increases before rain, the leaf pillows expand quickly and the leaves are easy to open. This will lead to different reactions of mimosa.

Many friends know that before heavy rain comes, the sudden drop in air pressure causes the pressure on the water to also decrease. Although the ancestors may not necessarily understand this truth, they have discovered through long-term observation that before heavy rains come, the green moss at the bottom of the river pond emerges in puffs due to the reduction in water surface pressure. Therefore, there is a popular weather farmer proverb among the people: "If there is moss on the bottom of the water, there will be heavy rain."

In summer and autumn, before a storm comes, observant people will see the gorgeous flowers of Pulian and Jade Curtain blooming. When they bloom such beautiful flowers, it is often a prelude to the typhoon heavy rain. Therefore, Pulian and Jade Curtain are known as "wind and rain flowers" among the people. When people see them blooming, they will be prepared to prevent typhoons and rains.

In southern my country, tung tree blooms around early to mid-April. At this time, strong cold air from the north often moves southward, resulting in rainy and low-temperature weather. Therefore, people named this phenological phenomenon "frozen tung flower". At this time, people will pay special attention to adding clothes to avoid catching a cold.

There is a plant called "Jingian " among the people. Those who are interested will find that in our northern region, frost usually falls about 10 days after it blooms. It can be said to be an expert at predicting the first frost. In our hometown, once Jerusalem artichoke blooms in autumn, it heralds the arrival of the first frost, so it’s time to harvest the vegetables quickly and wear more clothes to prevent the temperature from cooling down.

Many people will find that plum blossoms bloom early and late every year, late in cold winter and early in warm winter. Warm winter means cold spring and cold spring, and late spring cold often occurs. Therefore, plum blossoms bloom early, and a warm winter means more rain in spring, which is not good for spring sowing. The late blooming of plum blossoms reminds people not to miss the great opportunity for spring plowing and spring sowing to raise seedlings.

There is also the Quercus leucoides distributed in the south of my country. The color of its leaves is simply the "face" of weather changes. Local people will go to Quercus leucoides to "gain the wind and rain" when traveling.For example, before a heavy rain comes after a long drought, the leaves of Quercus leucoides will turn red. When the weather clears after the rain, the leaves turn dark green again, so the locals call it the "weather tree".

It turns out that the "changing face" of the leaves is because the proportion of chlorophyll and anthocyanins in the leaves has changed. We know that plant leaves contain chlorophyll and anthocyanins. Generally speaking, in autumn, the chlorophyll of trees decreases, and the anthocyanin-dominated leaves gradually turn red. However, the leaves of green are very sensitive. When encountering sultry weather before rain or low air pressure before a storm, the number of charged ions in the air increases, which affects the synthesis and decomposition of anthocyanins in the body. The synthesis of chlorophyll will be blocked, resulting in a change in the color of the leaves, and the leaves will gradually appear red.

There is a kind of wire grass plant, commonly known as "creeper". This kind of grass has nodes on the stem, roots are grown on the nodes, and it is spread flatly on the ground. In summer, it will turn itself into a dry state to reduce the transpiration caused by high temperature . When the air pressure decreases and the water vapor in the air increases, the wire grass will turn white due to water absorption. Therefore, when experienced people see the phenomenon of wire grass turning white, they will know that rainy days are coming.

There is a wonderful "wind and rain flower" growing in Xishuangbanna, Yunnan, my country. It has flat and slender leaves, pink flowers, purple-red bracts, and the flowers are shaped like narcissus, with six stamens with T-shaped anthers. When it is in full bloom, it looks like slender strips of lit wax, shining brightly. Whenever a storm is approaching, the wind and rain flowers will be full of energy and ready to bloom to welcome the coming of the storm. The arrival of wind and rain seems to sound the clarion call for its rapid opening, and its beauty remains unchanged despite the wind and rain. After the wind and rain, the colors are gorgeous, and the flowers are as red as clouds, reflecting red in the deep mountains and old forests.

In nature, in the eyes of botanists, the most intuitive and accurate flower weather forecaster is undoubtedly the "weather flower" of New Zealand . From the name of this flower, it can be seen that this flower has the characteristic of predicting winter rains. After long-term observation, people found that whenever its petals shrink and curl, heavy rain will come soon. And when its petals unfold, the sky will be clear that day. Therefore, local people will judge the weather conditions based on the changes in the shape of their petals when they go out.

To sum up: In nature, various magical plants often show us endless mysteries, waiting for humans to reveal them one by one. When people understand the ability of flowers to predict wind and rain, combined with local real-time weather forecasts, they can better serve people's lives and production. Do you know which plants have weather forecasting abilities? Everyone is welcome to share!
