Can plants predict the weather?

There are many plants that can predict the weather:

1. Wind Rain Flower: There is a wind rain flower in Xishuangbanna, China, which will bloom a lot before the heavy rain.

2. Moss: As the saying goes, "When water is covered with moss, there will be heavy rain." This is because before the rain, due to the sudden drop of temperature, the pressure on the surface of the pond decreased, resulting in moss at the bottom of the pond surface.

3. "Warm grass": Sweden has a kind of "warm grass" called Tricolor Ghost, which is extremely sensitive to temperature changes. When the temperature is above 20℃, the leaves extend obliquely upward; At 15℃, the blade moves down slowly until it is parallel to the ground; At 10℃, the blades extend obliquely downward.

4. Willow leaves: When walking by the river in summer, if you find that the willow leaves turn white, it may rain in the future. Because the willow leaves will all reverse before it rains, and the reverse side of the willow leaves is light green with a layer of "white frost" on the surface.

5. Artemisia annua: If the roots of Artemisia annua grow many tender buds, it indicates that it will rain.

6. Mimosa: Touch Mimosa with your hands. If the contraction is slow, or the leaves open immediately after closing, it indicates that it will rain.

7. Pumpkin vine: The top of pumpkin vine is generally upward in summer morning, indicating 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.

Of course, besides flowers and trees, grass can also predict the weather. For example, when there is a mildew ball at the intersection of the leaves and stems of Zoysia japonica, or when the leaves and stems of thatch are foaming, it indicates 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".
